河南省某县文化艺术中心结构设计

Structural design of a culture and art center in Henan province

河南省某县文化艺术中心地上4层,局部地下1层,结构高度为23.7m,采用混凝土框架-剪力墙结构体系。上部结构平面为近似旋转对称的切角三角形,边长约为180m,结构超长不设缝。结构存在扭转不规则、楼板不连续、竖向构件不连续等不规则情况,属于特别不规则的多层建筑结构。系统介绍了本项目结构设计的情况,并对关键问题进行了阐述和分析,包括楼层扭转位移比的正确统计、悬挑桁架验算及楼板在温度和地震工况下的应力分析,确保了结构设计的准确性和合理性。

The culture and art center in Henan Province has 4 floors above ground and 1 floor underground with a structural height of 23.7 m.The concrete frame-shear wall system is adopted.The superstructure plane is an approximately rotation-symmetric tangent triangle with a side length of about 180 m.The ultra-long concrete structure has no seismic joints.The structure has several irregular conditions such as irregular torsion,floor discontinuity and vertical component discontinuity,which is a particularly irregular multi-story building structure.The structure of the project is introduced,and key issues are explained and analyzed,including the correct statistics of the floor torsional displacement ratio,the cantilever truss calculation,and the floor stress analysis under the temperature and seismic conditions,to ensure the accuracy and rationality of the structure design.
