摘要
回顾了抗震计算中的几个主要结构动力学问题 ,单自由度和多自由度体系在地震作用下的动力分析 ;简要叙述了求解结构自振周期和振型的方法 ;提出架空斜坡码头抗震计算时的力学模型和计算简图 。
Reviewing the several main problems of dynamics in antiseismic calculation,the dynamic analysis of singe and multi freedom systems under the seismic action,the method for solving the self vibration period and vibration type of structure were expounded in the paper,the dynamic model and calculation scheme for the seismic calculation of overhead sloping wharf were raised for the reference of design.
