以具体工程为例,介绍一种新型装配式框架结构体系——高强混凝土预制管柱-钢梁混合装配式框架结构体系。采用SAP2000,MIDAS/Gen软件对该混合装配式框架结构的标准化框架模块进行了多遇地震下的弹性分析,并采用SAP2000软件对该混合装配式框架结构进行罕遇地震下的弹塑性时程分析。结果表明:高强混凝土预制管柱-钢梁混合装配式框架结构的延性和承载能力满足规范要求。技术经济比较结果表明,该混合装配式框架结构体系成本可控,具有较大的推广价值。
Taking concrete project as an example, this paper introduces a new type of fabricated frame structure system - high strength concrete prefabricated pipe string - steel beam hybrid assembly frame structure system. Using SAP2000 and MIDAS / Gen software, the flexible frame of the hybrid assembly-frame structure was subjected to the earthquake analysis and the SAP2000 software was used to analyze the elastic-plastic time history of the composite frame assembly under rare earthquakes . The results show that the ductility and bearing capacity of prefabricated high-strength concrete prefabricated pipe-steel beam composite fabricated frame structure meet the specifications. The technical and economic comparison shows that the cost of the hybrid assembly frame structure system is controllable and has a great promotion value.
