SIGNIFICANCE AND USE
10.1 Full-scale bending testing is an effective way to determine flexural properties of structural glued laminated timber (glulam) beams. However, testing of large glulam members is cost prohibitive. Mathematical models, when confirmed by full-scale test results, are useful tools to assign flexural properties for glulam. This practice provides guidelines for sampling and testing full-scale glulam beams to determine their flexural properties and to validate mathematical models intended for use in assigning flexural design values.
SCOPE
1.1 This practice describes procedures for full scale testing of structural glued laminated timber (glulam) to determine or verify characteristic values used to calculate flexural design properties. Guidelines are given for: (1) testing individual structural glued laminated timber lay-ups (with no modeling), (2) testing individual glulam combinations (with limited modeling), and (3) validating models used to predict characteristic values.
1.2 This practice is limited to procedures for establishing flexural properties (Modulus of Rupture, MOR, and Modulus of Elasticity, MOE). Some of the principles for sampling and analysis presented may be applicable to other properties. However, other properties may require additional testing considerations that are beyond the scope of this practice.
1.3 This practice is not intended to supersede the provisions of Practice D3737, but provides an alternative method for establishing characteristic values. Lay-up combinations developed in accordance with Practice D3737 are not required to be governed by this standard.
Note 1: The models described by Practice D3737 have been developed and modified based on more than 50 years of experience and many test programs. In some cases, however, it may be desirable to develop a new model based on other input properties or using lumber materials or grades not covered by that standard.
1.4 Details of production, inspection, and certification are beyond the scope of this document. However, for test results to be representative of production, quality control systems shall be in place to ensure consistent quality. Manufacturing shall conform to recognized manufacturing standards such as ANSI A190.1 or CSA O122.
1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This practice covers mechanics-based models for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam). The mechanics-based analyses shall account for the following: (1) stress-strain relationships for wood laminations and reinforcement; (2) strain compatibility; (3) equilibrium; (4) variability of mechanical properties; (5) volume effects; (6) finger-joint effects; (7) laminating effects; and (8) stress concentrations at the termination of reinforcement in beams with partial length reinforcement. This practice also provides for minimum physical test requirements to validate mechanics-based models. A minimum set of performance-based durability test requirements for reinforced glulams is also herein described. Additional durability test requirements shall be considered in accordance with the specific end-use environment.
SCOPE
1.1 This practice describes procedures for establishing the characteristic values for reinforced structural glued-laminated timber (glulam) beams using mechanics-based models and validated by full-scale beam tests. Glulam beams shall be manufactured in accordance with applicable provisions of ANSI A190.1.
1.2 This practice also describes a minimum set of performance-based durability test requirements for reinforced glulam beams, as specified in Annex A1. Additional durability test requirements shall be considered in accordance with the specific end-use environment. Appendix X1 provides an example of a mechanics-based methodology that satisfies the requirements set forth in this practice.
1.3 This practice is limited to procedures for establishing flexural properties (modulus of rupture, MOR, and modulus of elasticity, MOE) about the x-x axis of horizontally-laminated reinforced glulam beams.
1.4 The establishment of secondary properties, such as bending about the y-y axis, shear parallel to grain, tension parallel to grain, compression parallel to grain, and compression perpendicular to grain, for the reinforced glulam beams are beyond the scope of this practice.
Note 1: When the establishment of secondary properties is deemed necessary, testing according to other applicable methods, such as Test Methods D143 and D198 or analysis in accordance with Practice D3737, may be considered.
1.5 Reinforced glulam beams subjected to axial loads are outside the scope of this practice.
1.6 Proper safety, serviceability, and adjustment factors including duration of load, to be used in design are outside the scope of this practice.
1.7 Evaluation of unbonded, prestressed, and shear reinforcement is outside the scope of this practice.
1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The mechanics-based model shall be permitted to be developed using SI or inch-pound units.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 The properties evaluated by this test method are intended to provide comparative information on the effects of fire-retardant chemical formulations and environmental conditions on the flexural properties and IB strength of FRSC panels.
5.2 This practice uses a controlled elevated-temperature environment to produce temperature-induced losses in the mechanical properties of FRSC panels and untreated panels.
5.3 Prediction of performance in natural environments has not been directly correlated with the results of this test method.
5.4 The reproducibility of results in elevated-temperature exposure is highly dependent on the type of specimens tested and the evaluation criteria selected, as well as the control of the operating variables. In any testing program, sufficient replicates shall be included to establish the variability of the results. Variability is often observed when similar specimens are tested in different chambers even though the testing conditions are nominally similar and within the ranges specified in this test method.
SCOPE
1.1 This test method is designed as a laboratory screening test. It is intended to establish an understanding of the respective contributions of the many wood material, fire-retardant, resin and processing variables, and their interactions, upon the mechanical properties of fire-retarded mat-formed wood structural composite (FRSC) panels as they affect flexural and internal bond (IB) performance and as they are often affected later during exposure to high temperature and humidity. Once the critical material and processing variables have been identified through these small-specimen laboratory screening tests, additional testing and evaluation shall be required to determine the effect of the treatment on the panel structural properties and the effect of exposure to high temperature on the properties of commercially produced FRSC panels. In this test method, treated structural composite panels are exposed to a temperature of 77°C (170°F) and at least 50% relative humidity.
1.2 The purpose of the preliminary laboratory-based test method is to compare the flexural properties and IB strength of FRSC panels relative to untreated structural composite panels with otherwise identical manufacturing parameters. The results of tests conducted in accordance with this test method provide a reference point for estimating strength temperature relationships for preliminary purposes. They establish a starting point for subsequent full-scale testing of commercially produced FRSC panels.
1.3 This test method does not cover testing and evaluation requirements necessary for product certification and qualification or the establishment of design value adjustment factors for FRSC panels.
Note 1: One potentially confounding limitation of this preliminary screening test method is that it may be conducted with laboratory panels that may not necessarily represent commercial quality panels. A final qualification program should likely be conducted using commercial quality panels and the scope of the review should include evaluation of the effects of the treatment and elevated temperature exposure on all relevant mechanical properties of the commercially produced panel.
1.4 This test method is not intended for use with structural plywood.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This practice covers mechanics-based models for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam). The mechanics-based analyses shall account for the following: (1) stress-strain relationships for wood laminations and reinforcement; (2) strain compatibility; (3) equilibrium; (4) variability of mechanical properties; (5) volume effects; (6) finger-joint effects; (7) laminating effects; and (8) stress concentrations at the termination of reinforcement in beams with partial length reinforcement. This practice also provides for minimum physical test requirements to validate mechanics-based models. A minimum set of performance-based durability test requirements for reinforced glulams is also herein described. Additional durability test requirements shall be considered in accordance with the specific end-use environment.
SCOPE
1.1 This practice covers mechanics-based requirements for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam) manufactured in accordance with applicable provisions of ANSI/AITC A190.1, subjected to quasi-static loadings. It addresses methods to obtain bending properties parallel to grain, about the x-x axis (Fbx and Ex) for horizontally-laminated reinforced glulam beams. Secondary properties such as bending about the y-y axis (Fby), shear parallel to grain (F vx and Fvy), tension parallel to grain (Ft), compression parallel to grain (Fc), and compression perpendicular to grain (Fc⊥) are beyond the scope of this practice. When determination of secondary properties is deemed necessary, testing according to other applicable methods, such as Test Methods D143, D198 or analysis in accordance with Practice D3737, is required to establish these secondary properties. Reinforced glulam beams subjected to axial loads are outside the scope of this standard. This practice also provides minimum test requirements to validate the mechanics-based model.
1.2 The practice also describes a minimum set of performance-based durability test requirements for reinforced glulams, as specified in Annex A1. Additional durability test requirements shall be considered in accordance with the specific end-use environment. Appendix X1 provides an example of a mechanics-based methodology that satisfies the requirements set forth in this standard.
1.3 Characteristic strength and elastic properties obtained using this standard may be used as a basis for developing design values. However, the proper safety, serviceability and adjustment factors including duration of load, to be used in design are outside the scope of this standard.
1.4 This practice does not cover unbonded reinforcement, prestressed reinforcement, nor shear reinforcement.
1.5 The values stated in SI units are to be regarded as standard. The mechanics based model may be developed using SI or in.-lb units.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
Full-scale bending testing is an effective way to determine flexural properties of structural glued laminated timber (glulam) beams. However, testing of large glulam members is cost prohibitive. Mathematical models, when confirmed by full-scale test results, are useful tools to assign flexural properties for glulam. This practice provides guidelines for sampling and testing full-scale glulam beams to determine their flexural properties and to validate mathematical models intended for use in assigning flexural design values.
SCOPE
1.1 This practice describes procedures for full scale testing of structural glued laminated timber (glulam) to determine or verify characteristic values used to calculate flexural design properties. Guidelines are given for: (1) testing individual structural glued laminated timber lay-ups (with no modeling), (2) testing individual glulam combinations (with limited modeling), and (3) validating models used to predict characteristic values.
1.2 This practice is limited to procedures for establishing flexural properties (MOR and MOE). Some of the principles for sampling and analysis presented may be applicable to other properties. However, other properties may require additional testing considerations that are beyond the scope of this practice.

ABSTRACT
This practice covers mechanics-based models for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam). The mechanics-based analyses shall account for the following: (1) stress-strain relationships for wood laminations and reinforcement; (2) strain compatibility; (3) equilibrium; (4) variability of mechanical properties; (5) volume effects; (6) finger-joint effects; (7) laminating effects; and (8) stress concentrations at the termination of reinforcement in beams with partial length reinforcement. This practice also provides for minimum physical test requirements to validate mechanics-based models. A minimum set of performance-based durability test requirements for reinforced glulams is also herein described. Additional durability test requirements shall be considered in accordance with the specific end-use environment.
SCOPE
1.1 This practice covers mechanics-based requirements for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam) manufactured in accordance with applicable provisions of ANSI/AITC A190.1, subjected to quasi-static loadings. It addresses methods to obtain bending properties parallel to grain, about the x-x axis (Fbx and Ex) for horizontally-laminated reinforced glulam beams. Secondary properties such as bending about the y-y axis (Fby), shear parallel to grain (F vx and Fvy), tension parallel to grain (Ft), compression parallel to grain (Fc), and compression perpendicular to grain (Fc) are beyond the scope of this practice. When determination of secondary properties is deemed necessary, testing according to other applicable methods, such as Test Methods D 143, D 198 or analysis in accordance with Practice D 3737, is required to establish these secondary properties. Reinforced glulam beams subjected to axial loads are outside the scope of this standard. This practice also provides minimum test requirements to validate the mechanics-based model.
1.2 The practice also describes a minimum set of performance-based durability test requirements for reinforced glulams, as specified in . Additional durability test requirements shall be considered in accordance with the specific end-use environment. provides an example of a mechanics-based methodology that satisfies the requirements set forth in this standard.
1.3 Characteristic strength and elastic properties obtained using this standard may be used as a basis for developing design values. However, the proper safety, serviceability and adjustment factors including duration of load, to be used in design are outside the scope of this standard.
1.4 This practice does not cover unbonded reinforcement, prestressed reinforcement, nor shear reinforcement.
1.5 The values stated in SI units are to be regarded as standard. The mechanics based model may be developed using SI or in.-lb units.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
