本文运用经改进后可以计算结构弹塑性能量时程反应的数值积分法计算程序,分別把实际地震记录和人工地震波输入到八座在唐山地震中遭受不同程度破坏的实际结构计算模型中,进行结构弹塑性变形和能量反应的计算。将计算结果和实际震害情况相比较,从中探讨并得到同时考虑结构的变形能力和累积塑性耗能、较便于实际应用的双重破坏控制指标。
In this paper, the numerical integral method for calculating the time-history response of structural elastoplastic energy can be used to calculate the program. The actual seismic records and artificial seismic waves are input into eight actual structural calculation models subjected to different degrees of damage in the Tangshan earthquake. Elasto-plastic deformation and energy response calculations. Comparing the calculated results with the actual seismic damage situation, the dual destruction control index that simultaneously considers the structural deformability and accumulated plastic energy consumption and is more convenient for practical application is discussed.
