Research On Construction Technique For Suspended Cantilevered Structures Of Chongqing Cathay Art Center

The suspended cantilevered structure has been more and more applied in project because of its good structural behaviour and unique visual impact.As the complex form of the suspended cantilevered structure and many construction difficulties,the influence of construction forces on the structure of the force and deformation can't be ignored. Therefore, it has important significance that mechanics analysis is adopted for the kind project during construction period to ensure project quality and safety.Based on the suspended cantilevered structures of Chongqing Cathay Art Center, this paper presents the following work:â‘ At first, the research of the domestic and foreign suspended cantilevered structures are summarized. Not only the developing process, the structural features of suspended cantilevered structures but also the construction process mechanical analysis are introduced.â‘¡The project features, the construction process and the construction key points of suspended cantilevered structures are described. The construction technical contains the selection of vertical transportation systems, bagging control, space support systems, construction survey, installation and welding techniques. The selection principles, control purposes, specific methods and design elements of key technologies are discussed in detail, which provides the basis to adopt the construction successfully in the suspended cantilevered structure.â‘¢Not only the basic principles of construction process mehanical, but also the model simplification, the load combination selection and the contruction stage defined are systematically elaborated,putting forth the analysis methods and process about contruction mechanical simulation.And then it is proved by using this technology in the project of Chongqing Cathay Art Center, it is necessary consider the impact of construction process factors.â‘£This behavior of supported jig frame for suspended cantilevered structure is researched.The finite element software SAP2000 is adopted to determine jig frame form and node connection.The some basic rules and requirement of the unloading process and the implementation plan in the construction Process of the suspended cantilevered structure in Chongqing Cathay Art Center are analyzed.The finite element software SAP2000 is adopted to establish theoretical caleulation model and simulate the unloading Proeess The reasonable order of demolishing the temporary supports and unloading quantity in each unloading were determined by the numerieal simulation analysis of unloading Proeess.
