摘要
本文简要介绍了一典型钢筋混凝土框架结构加层改造的抗震评价。针对加层后的结构,提出了通过控制位移的抗震加固措施,时程分析结果表明,加固后结构能满足规范的抗震要求。
In this paper, seismic analysis about a typical reinforced concrete frame structure of enlarging floors is introduced. A strengthening method by controlling the structure's displacement is put forward, and earthquake response after structural retrofitted is computed. The results prove the approach presented here could improve the ability to resist earthquake and ensure the safe utilization of the structure.
