摘要
通过对国内外木质工字梁的研究现状进行归纳和分析,总结了木质工字梁的设计规范及材料、连接方式、截面尺寸、腹板开孔和环境对梁物理力学性能、应用性能及耐久性能(蠕变)的影响。同时阐述了竹质工字梁的设计与制造技术,物理力学性能检测与评估等方面的研究进展。
Through summarizing and analyzing the research status of wooden I-beam at home and abroad,the design specification of wooden I-beam,as well as the influence of materials,connection mode,section size,web opening and environment on the physical and mechanical properties,application performance and durability(creep)of the beam are summarized.This paper also describes the research progress of bamboo I-beams in designing and manufacturing technology,the testing and evaluation of physical and mechanical properties.
