循环荷载作用下钢结构滞回性能的数值模型

Numerical model for the hysteretic behaviour of steel structures under cyclic loading

提出了“塑性铰有限分布”的数值模型用以分析钢结构在循环荷载作用下的滞回性能。经与试验结果比较表明模型简单、易于实施，待进一步完善后，可直接用于对梁及压弯构件的模拟。

A numerical model using plastic block finite distributed length is presented for the simulation ofthe behaviour of steel structures under cyclic loading. A comparison between the numerical results and theexperimental tests is made.COmparative results show that model is simple and feasible for use.
