摘要
沈阳艺术文化中心的混凝土主体结构由四个混凝土剪力墙筒体作为主要的抗侧力构件,含大跨度高位悬挑多楼层结构。根据振动台试验尺寸要求,建立了大跨度悬挑结构有限元模型,采用NosaCAD和ABAQUS进行了动力弹塑性结构分析和对比。同时,制作1/30的缩尺模型进行振动台试验研究,研究结构的薄弱环节。理论分析和试验研究表明,该结构在地震作用下可满足现行规范要求,结构布置及分析方法可供今后类似工程借鉴。
The concrete main structure of Shenyang Art and Culture Center consists of four concrete shear wall tubes as the main lateral force resisting members,including a large-span high cantilever multi-storey structure.According to the size requirements of shaking table test,the finite element model of large-span cantilever structure is established in this paper.The dynamic elastoplastic structure analysis and comparison are carried out using NosaCAD and ABAQUS.At the same time,a 1/30 scale model was made for shaking table test research to study the weak links of the structure.The theoretical analysis and experimental study show that the structure can meet the requirements of the current code under earthquake action,and the structural layout and analysis method can be used for reference by similar projects in the future.
