本文绘出14片悬臂深梁在一次加载和反复加载下的试验结果。讨论破坏形态，分析受力性能，提出承载力计算公式，计算值与试验值符合良好。在试验基础上提出悬臂深梁设计方法，并应用于上海博物馆工程16片悬臂深梁设计。根据模拟关系近似估计实际的悬臂深梁的承载能力及大体的安全储备，对设计提出改进意见，供工程应用及修订规范参考。 This paper plots the test results of 14 cantilever deep beams under one loading and repeated loading. Discussion of damage patterns, analysis of mechanical properties, proposed formula for calculation of bearing capacity, and the calculated values ​​are in good agreement with the experimental values. Based on the experiment, a design method of cantilever deep beams was proposed and applied to the design of 16 cantilever deep beams of Shanghai Museum Engineering. Based on the simulation relationship, the actual bearing capacity of the cantilever deep beam and the general safety reserve are approximated, and suggestions for improvement are provided for the design, for engineering application and revision of the normative references.
