摘要
本文提出利用刚度的调整将输入结构中的地震能量转移集中于结构不太重要的部位进行耗散。并利用线性随机振动分析和非线性逐步积分的方法对结构的能量分布进行了详细的分析。求出了刚度最优调整值。数值模拟结果表明此方法是非常有效的。
In this paper, a view of collecting or shifting the seismic energy in structure to therelatively unimportant part of the structure is presented. And for this purpose, themethode is also presented to change the stiffness of structures. In this paper, the distri-bution and the shift of energy are analyzed in detail by means of both the linear stochas-tic vibration program and the step by step integration program. The optimum stiffnessis calculated, and the results show this methode is very efficient.
