【摘要】 宿迁学院新校区图书馆项目为新型立面悬索-钢框架混合结构，为实现其顺利施工，提出了一种采用少量临时支撑架周转连续施工的方法。采用SAP2000软件建立结构有限元模型，对比研究施工过程模拟方法，并对周转所需临时支撑架层数、悬索张拉及其上部钢梁安装顺序等关键技术进行研究。对结构施工全过程进行模拟并分析结构响应，重点关注4个立面悬索结构，掌握结构状态，验算承载力和变形。结果表明，采用新安装单元两步激活法可更好地模拟实际施工过程；采用2层支撑架周转施工且悬索张拉先于其上部钢梁安装，可顺利实现结构施工并有效减少支撑架投入；施工过程中钢结构应力、索力、结构位移均在合理控制范围内；结构施工完成后与设计状态基本一致，验证了施工方法的合理性和可行性。更多还原

【Abstract】 The library project of Suqian College new campus is a new type of facade suspension cable-steel frame hybrid structure. In order to achieve its smooth construction, a method of using a small number of temporary support frames for continuous construction was proposed. Using SAP2000 software to establish a finite element model of the structure, a comparative study was conducted on the simulation methods of the construction process, and key technologies such as the number of temporary support frames required for turnover, suspension tensioning and the installation sequence of it’s upper steel beams were studied. The entire construction process of the structure was simulated and the structural response was analyzed, with a focus on four facade suspension structures. The structural status was grasped, and the bearing capacity and deformation were verified. The results indicate that using the two-step activation method for new installation units can better simulate the actual construction process.The use of a 2-layer support frame for turnover construction and the installation of suspension cables before the upper steel beams can smoothly achieve structural construction and effectively reduce the investment in support frame equipment.During the construction process, the stress, cable tension, and structural displacement of the steel structure are all within a reasonable control range.After the completion of structural construction, it is basically consistent with the design status, which verifies the rationality and feasibility of the construction method.更多还原
