摘要
某混凝土框架结构体系主体总高14m,总长77.5m,横向两跨,纵向十跨,采用独立基础设计。利用软件建立结构加固模型,对原结构、钢支撑加固结构和摇摆墙加固结构进行弹性和弹塑性分析,结果显示钢支撑加固和摇摆墙加固均可提高结构抗震承载力,但钢支撑加固法仍可能形成层屈服破坏机制,而摇摆墙加固法更有优势。
The main body of a concrete frame structure is 14 m high and 77.5 m long.It adopted independent foundation design and transversely crosses two spans and longitudinally ten spans.Software was used to establish structure strengthening model and to analyze the elasticity and elastoplasticity of the original structure,steel support strengthening structure and rocking wall strengthening structure.It was found that both steel support and rocking wall could improve the aseismic bearing capacity of structure.Steel support might form floor yield failure mechanism,so rocking wall has better strengthening effect than steel support.
