摘　　要：就H形断面钢柱在循环荷载作用下,对危险点处的应变累积史及整体承载力进行了全过程试验分析,获得了几个重要状态下的应变累积值,为钢结构的塑性设计及选择理论计算模型提供了有价值的参考资料.同时还解决了交变性大应变的测试方法.The complete process experimental analysis of strain cumulation history and bearing capacity of dangerous point of H-cross-section steel pillar under cyclic load has been completed. The several strain cumulation numbers with differeret key condition were obtained. The results provide the basis reference for optimizing the plastic design of steel structure and choice of mathematical model. At the same time, measurement methods of cycle large strain have been solved.
