摘要
使用软件SAP对某12层混凝土框架现浇结构进行时程和模态分析,结果可知,模拟的模态参数满足相应规范的要求;振型数据显示,地震灾害时,使用软件模拟得出最大楼层间的位移角,通过层间位移角数值的不同对地震预警器进行规划放置;对不同楼层的加速度进行统计,验证地震作用下数据的合理性。分析模拟结果可知,地震预警器应该安排在3层,4层,5层,6层,11层,12层。
Use the software SAP of a 12 storey concrete frame structure cast-in-place process and modal analysis results,the modal parameters of the simulation meet the requirements of the corresponding standard;modal data show that the earthquake disaster,the use of software to simulate the maximum floor displacement angle between the earthquake warning device,planning is placed through the interlayer displacement angle numerical analysis of different;different acceleration floors,verify the seismic data.The simulation results show that the earthquake ear原ly-warning device should be arranged in the 3,4,5,6,11 and 12 layers.
