Study on Simplified Method of Determining Strengthening Design Ground Motion Parameters for Existing Buildings

采用理论研究的方法计算现役结构抗震加固设计地震动参数,会给实际工程设计人员带来麻烦,也不符合工程设计人员对规范的使用习惯。本文以前期的理论计算为基础,提出了确定现役结构抗震加固设计地震动参数的简化方法,给出了与抗震设计规范结合使用的地震动参数调整系数。通过算例分析,对理论方法、规范方法和简化方法进行了比较,验证了简化方法的可行性,便于实际工程加固设计时采用。

Determining strengthening design ground motion parameters using theory method is not convenience of project planner. In order to easy to employin engineering application, the simplified method of determining strengthening design ground motion parameter is put forward, and ground motion parameter adjusting coefficients that can be use combined with seismic design code are provided. At the same time, by means of calculation example, the application method of the adjusting coefficient is presented. Then, the theory method, the code method and the simplified method are compared, and the simplified method is verified.
