摘要
介绍了抗地震设计分析常用的响应谱方法。对某工程安全水鼓型滤网进行了分析,改进了原设计不合理部分。通过减弱设备刚度避开了地震能量集中区,增加了设备的抗震能力,减小了设备对基础的冲击力,上述改进已被正式采用。
Abstract This paper described the usual analysis method of response spectrum used in against earthquake design,and the seismic response analysis of the drum shaped filters used in a power generating station was proceed.The old design plan was improved,the stiffness of the device was decreased so that the main frequency was below the rang of high energy concentration in the response spectrum.The against earthquake ability of the device was enhanced.The seismic force passed to the base was reduced largely.This scheme has been adopted.
