本文以国内历年来所进行的木结构轴心压杆试验结果为基础,结合我国建筑用木材树种情况,分析研究提出轴心压杆按树种而不同的A、B、C三条φ值曲线,并对四种树种进行了结构可靠度验算。其结果可作为修订木结构设计规范的依据。 In this paper, based on the results of the axial compression test of wooden structures carried out over the years in China, combined with the conditions of timber species used in construction in China, the three A, B, and C φ curves of the axial compression bars according to tree species are analyzed and studied. Structural reliability of the four tree species was checked. The results can be used as the basis for the revision of wood structure design specifications.
