高层钢-混凝土组合结构等高同步施工的时变效应与力学性能
Time-dependent effects and mechanical behavior of high-rise steel-concrete composite structures during synchronized rising construction
摘要
Abstract
To address the technical challenge of coordinated work between two different materials,the con-crete tube and the outer frame steel columns,and to ensure the safety of the structure during the construction stage and meet the design requirements at the completion stage,a synchronized rising construction system is proposed.Taking the Nanjing Jiahua G72 Project as a specific engineering research object,this paper con-ducted computational simulation analysis and mechanical behavior research on the super high-rise hybrid struc-ture system that applied this technology,and discussed the rationality of the synchronized rising construction technology in this type of structure system.The results show that the key joints of the steel frame-concrete wall possess sufficient reliability during the construction process.The vertical deformation of both the core tube and the outer frame presents a curve distribution trend similar to a fish-belly shape.Concrete with different ages has little influence on shrinkage and creep.Compared with the traditional advanced-floor construction method,the synchronized rising construction technology has a certain control advantage in terms of vertical de-formation,which can meet the safety and reliability requirements of the structure during the construction stage and when it enters the service stage after completion.The research results provide technically practical and guiding references for the construction of subsequent similar projects.关键词
