连接形式对扩建多层砖房抗震性能的影响

Horizontal connecting type’s influence on seismicperformance of extension multistoried brick buildings

结合某扩建工程实例分析了连接形式对扩建多层砖房抗震性能的影响 ,结果表明 :当扩建部分的高宽比过大时 ,连接形式是影响结构抗震承载能力的关键因素。根据研究结论和工程实践 ,对扩建多层砖房的抗震设计及施工提出了建议。

For extension multistoried brick buildings in seismic region,horizontal connection between the extension and previous building is very important. This paper analyses theoretically connecting type’s influence on the seismic behaviors of extention multistoried brick buildings,the analytical results indicate that when the depth-width ratio of the extension is large,the connecting type become the main effect factor of the seismic bearing capability.Based on the results and engineering practice,some recommendations for seismic design and construction of extension multistoried brick buildings are presented.
