某在建地铁车站动力特征响应分析

A study on seismic response of subway station

按照建筑结构荷载规范,选取了昆明某在建地铁的最不利荷载工况,基于ANSYS有限元软件,对该地铁车站进行了地震作用下的动力时程分析,结果表明:该地铁车站整体位移很小且振动非常稳定,在该地区能够实现"小震不坏,中震可修,大震不倒"抗震设防原则。

Select the worst load effect combination for the Kunming metro station based on the load code for the design of building structures, carry out the elastic dynamic time-history analysis for the metro station using the software ANSYS. The results show that the metro station can achieve the principle of three level fortification as three states of work： safety（ undamaged） , intermediate（ repairable） and failure（ destruction） as the little global response and stable vibration.
