某医院结构改造加固设计

重点设防类建筑的结构改造加固设计过程中,后续使用年限对地震影响系数(αmax)及抗震措施均有相应的折减系数,其对复核计算中地震力效应及选取加固方案均有相应影响。加固设计应首先满足结整体承载力规范要求,然后再针对单个构件承载力进行分析。文中介绍了加固设计涉及的增大截面法、外粘型钢法等加固方法。

A Hospital Structure Reinforcement Design

The structure of key fortification class building renovation and design process,use fixed number of year subsequent to the earthquake influence coefficient（ αmax） and aseismatic measures all have corresponding reduction factor,the check computation of seismic force effect and reinforcing scheme are selected corresponding effect.Reinforcement design should first meet and overall capacity meet the specification requirements,and then on a single component bearing capacity is analyzed.This paper introduces the reinforcement design of enlarged cross section method,the method of sticking steel strengthening methods,etc.
