摘要
本文主要介绍在我院力学-结构试验中心首次进行的钢框架子结构伪动力试验。试验中采用等效单自由度方法对试验部分与计算部分界面处整体倾覆弯矩进行了模拟。通过与相应的振动台试验和电算分析进行比较,说明本次伪动力试验是成功的,等效单自由度方法能较准确地模拟子结构伪动力试验的界面整体倾覆弯矩。
This paper introduces a steel frame model PSD test carried out by the equivalent SDOF substructural PSD test method. The test results are compared with those of the shaking table test as well as the computer analyses, which show that the results from the three ways have a better correspondency, and the equivalent SDOF method can simulate the whole overturning moment in substructural PSD test correctly.
