地震荷载作用下MDOF结构的弹塑性时程分析
Analysis of MDOF structural plastic character under effect of earthquake load
【摘要】 对多自由度剪切型结构在地震荷载下的响应分析采用了数值分析方法,给出了绝对位移线性加速法的计算公式和步骤,并将该算法的实例结果和振型分解法的实例结果进行了比较,通过比较发现该算法可以监测和预报地震灾害的发生过程。
【Abstract】 It adopts maths analyzing methods to analyze multi-free cutting mode structure under effect of earthquake load,brings forward the formular and procedure of absolute movement speed-up method,and compares the actual results between this calculation and shaking dissolution method.The result shows,this calculation could supervise and prospect the happening process of earthquake.
