(河南省医药设计院 郑州 450003)[提要] 对砌体规范中梁端砌体局部受压计算时N0与 φ 的取值,在深入辨明其物理意义的基础上,对规范背景资料模拟试验结果作出不同的分析推演,得出按规范公式计算时多数情况偏于不安全的结论。试提出修订公式,以求商榷。
[关键词] 砌体局压 上部轴向力 荷载 折减系数 修订公式To count N0 and φ for calculating local compression of masonry at the end of beam, in according with the code for masonry, and on the basis of having a thorough understanding of their physical meanings, author makes different analyses and deliberations on the results of simulated tests in the code background. The calculated results from the code formulas in many cases are proved unsafe. Here are revisal formulas to be submitted for discussion.
