【摘要】 针对某29层的钢筋混凝土筒体结构建筑,在建立空间杆系—层模型的基础上,对三种不同水平加强层设置的混凝土超高层筒体结构进行地震作用下的计算分析,并对不同结构布置进行比较,总结出此类超高层结构在设置加强层后结构内力及抗震性能的变化规律,对带加强层筒体结构的设计和构造措施作一些探讨.更多还原

【Abstract】 According to a 29-storey building of reinforced concrete tubing structure,a spatial member-storey model is built.By using the model,arithmetic and seismic analysis is made with regard to concrete tubing structures of three kinds of level super high-rise strengthened storey.The changes of internal force and the seismic performance are also studied by comparing the three kinds of structures with different arrangements.Besides,when the super high-rise structures are strengthened,the law of changes in the structural internal force and seismic performance is drawn.This paper also discusses design and construction methods of how to strengthen such buildings.更多还原
