【摘要】 针对单自由度结构系统,定性讨论了一致地震动输入模式之间的关系、对体系响应的影响及相关问题。主要结论为:一致地震动输入的位移与加速度之间必须较好地满足运动学关系;宜采用位移输入模式计算长周期体系的地震响应;宜采用加速度输入模式计算短周期体系的地震响应。更多还原

【Abstract】 For the single degree of freedom structural systems,the paper qualitatively discusses about the relations of the consistent ground motion input modes,their effects on system response,and the related issues.Primary conclusions are: the displacement and acceleration input modes of the consistent ground motion must well satisfy the kinematic relations;the displacement input mode is proper for calculating seismic response of long period system;the acceleration input mode is proper for calculating seismic response of short period system.更多还原
