摘要

目的研究适合带底部薄弱层房屋结构的经济、有效和实用的抗震试验方法-试验子结构为单自由度、计算子结构为多自由度的结构拟动力试验方法.方法应用PCM-Newmark法作为实现上述子结构拟动力的数值算法.结果推导出了基于PCM-Newmark法的试验子结构为单自由度、计算子结构为多自由度的结构拟动力试验方法,给出了矩阵求解过程.结论试验子结构为单自由度、计算子结构为多自由度的子结构拟动力试验方法由于在试验中仅需取薄弱层部分作为试验子结构,经济优势明显.实例分析表明,这种子结构拟动力试验方法稳定可靠,且可以方便地得到全结构各层的加速度、速度和位移的地震反应.
This paper studies economical,valid and practical seismic testing method of building with first-soft-story,the substructure pseudodynamic testing method with its PSD tested part of the testing structure is SDOF structure and the numerically operated part is MDOF.PCM-Newmark algorithm was used in the pseudodynamic testing.This substructure pseudodynamic testing programe is offered and the matrix solving method is provided.This substructure pseudodynamic testing method is economical because of taking first-soft-story as PSD tested part.This method is reliable and the dynamic response can be obtained veritably.
