摘要
本文按有限输入方向计算并采用线性予测的方法讨论了两向地震对平-扭耦联系统动力反应的影响.通过实例计算说明:弹塑性结构受地震波输入方向的影响显著大于相应弹性结构.对弹塑性结构而言,在本质上不存在确定不变的最不利地震波输入方向.
Based on the limited imput directions and linear estimate method, the paper examines the effects of the imput direction of bi- directional earthquake wave to the dynamic response of torsional coupling system. The calculations show that the effects is very large for elastoplastic structure as compared with the same elastic structure, and yet, for elastoplastic structures, the definite worst imput direction does not exist.
