摘要
针对国家标准抗震设计规范的要求,采用弹塑性时程分析方法对结构进行分析模拟.考虑影响时程分析可靠性的因素,探讨目前地震动选择方案的合理性.基于当前选波方案存在的缺陷,并考虑持时的影响,采用弹性总输入能对选波方案进行补充.理论与模拟分析表明,所提出的选波方案全面地考虑了地震动3个因素影响,而且结构计算结果更合理.
According to the reqiurements of the code for seismis design of buildings, the elasto-plastic time-history method is adopted to analyse the structure. Considering the factors influencing the reliability of the time-history method, the rational selection method of seismic wave is studied. In order to improve the defects of current selection of seisimic wave, it is suggested to use the elastic total input energy as the complemental method under consideration of the influence of motion duration. A nonlinear soft IDARC program is carried out. Both theoretical and computational analyses show： this selection method of seismic wave considers three factors of ground motion comprehensively, therefore the computational results are reasonable.
