[提要]  對砌體規(guī)范中梁端砌體局部受壓計算時N₀與 φ 的取值，在深入辨明其物理意義的基礎(chǔ)上，對規(guī)范背景資料模擬試驗結(jié)果作出不同的分析推演，得出按規(guī)范公式計算時多數(shù)情況偏于不安全的結(jié)論。試提出修訂公式，以求商榷。
[關(guān)鍵詞]  砌體局壓 上部軸向力 荷載 折減系數(shù) 修訂公式

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.
Keyowrds: masonry; local  compression; upper normal  force; decreased  coefficient;.revisal formulas
