砖结构是一种历史悠久、使用广泛的建筑结构。但是,关于砖结构的一个基本力学性能指标——泊松系数μ值,尚无一个确定的数值。1976年唐山地震以来,许多研究设计单位在砖石结构房屋抗震研究、设计和加固工作中,急需一个较为准确的μ值,以便深入探讨砖结构在水平地震力作用下的受力特性及其墙体的破坏机理和抗剪强度。1977年5月在河北廊坊召开的“抗震研究计划”协调会议上,提出了本研究项目,并下达给我所。现行砖石结构设计规范(GBJ 3-73)中也缺这个数据,将来修订规范时,需要补
Brick structure is a long-established, widely used building structure. However, there is no definite value for a basic mechanical property index of the brick structure, the Poisson coefficient μ. Since the Tangshan earthquake in 1976, many research and design institutes urgently needed a more accurate μ value in the seismic study, design, and reinforcement of masonry structures in order to investigate in depth the stress characteristics of the brick structure under the horizontal seismic force and its wall. Body damage mechanism and shear strength. In May 1977, at the “Anti-seismic Research Program” coordination meeting held in Langfang, Hebei Province, this research project was proposed and submitted to the Institute. This data is also missing in the current Code for Design of Masonry Structures (GBJ 3-73). In the future revision of specifications, it is necessary to make up
