Using the triangle pulse as the substitute of the major motion pulse,the dynamic analytical resolution of the elastic SDOF system under bi-triangle pulse excitations is presented.
对地震作用下结构破坏的特征及强震记录进行分析,指出对脉冲型地震动中主震脉冲的作用效应进行研究的必要性;利用三角脉冲作为强震主脉冲的理论简化,给出双三角脉冲作用下单自由度弹性体系的动力反应解析解;采用研究反应谱变化规律的方法,分析两类脉冲组合即:波前脉冲组合以及波后脉冲组合,总结归纳出波前脉冲与波后脉冲对主脉冲作用效应的不同贡献规律,为进一步研究揭示脉冲型地震动中主脉冲的破坏能力奠定了基础。
