1.1 本规程描述了使用基于力学的模型并通过足尺梁试验验证的加固结构胶合层压木材（glulam）梁的特征值的建立程序。应根据ANSI A190.1的适用规定制造集成材梁。 1.2 本规程还描述了一组最低的基于性能的加固集成材梁耐久性试验要求，如 附件A1 . 应根据具体的最终使用环境考虑额外的耐久性测试要求。 附录X1 提供了一个力学示例- 基于满足本实践中规定要求的方法。 1.3 本规程仅限于确定水平层压增强集成材梁x-x轴周围弯曲性能（断裂模量MOR和弹性模量MOE）的程序。 1.4 加固的集成材梁的次要性能的确定，例如围绕y-y轴的弯曲、平行于晶粒的剪切、平行于晶粒的张力、平行于晶粒的压缩和垂直于晶粒的压缩，超出了本规程的范围。 注1: 当认为有必要建立二次特性时，根据其他适用方法进行测试，例如测试方法 D143 和 D198 或根据实践进行分析 D3737 ，可以考虑。 1.5 承受轴向荷载的加固集成材梁不在本规程范围内。 1.6 设计中使用的适当安全性、可用性和调整系数（包括负载持续时间）不在本规程的范围内。 1.7 无粘结、预应力和抗剪钢筋的评估不在本规程的范围内。 1.8 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 应允许使用SI或英寸-磅单位开发基于力学的模型。 1.9 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.10 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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.
