摘要
本文主要针对海洋结构非线性随机地震响应问题的近似计算分析进行了研究,导出了一个求解等效阻尼系数的简单表达式,利用这一等效阻尼系数,就可直接求解非线性结构的随机地震响应,而不必进行反复的迭代。这一方法的优点是求解过程较简单,计算速度快,但又具有较高的精度。
In this paper,the method of approximate calculation for nonlinear random earthquake responses of offshore structures is studied.A simple expression for equivalent damping coefficient is deduced.Using this expression,the random responses of the structures to earthquake can be evaluated directly without any iteration.Simple solution process and high accuracy are main advantages of this method.
