摘要
通过单跨框架结构加层改造的工程实例,论述了克服装配式楼盖、单跨框架结构房屋整体性能差、受力性能差的措施,采用多种加固措施对房屋进行加固改造,不拘泥于已有的建筑结构设计模式,将原建筑刚度薄弱处采用改变原墙体构造以增强结构刚度,使房屋楼盖刚度均匀,改善结构体系,同时采用增设柱间钢支撑的方式,增加抗震设防防线,加强房屋抗震性能,不仅满足了结构的受力要求,而且减少了对柱的冗余加固,使改造加固方案达到技术先进、经济合理、安全适用,节约了加固的费用,取得了良好的技术和经济效益。
Through the project example of a single span frame structure, the measures to overcome the weak overall performance of the assembling floor system and single span frame structural building were discussed. Various strengthening measures to strengthen and reform the building, such as the measure that change the original wall s structure to strengthen the structure s stiffness at the weak places, the measure to make the building floor system s stiffness homogeneous and improve the structural system, the way ...
