地下室嵌固作用对不规则结构下的侧向刚度的影响

对于带有地下室的高层、超高层和复杂多层建筑结构,在设计计算中如何考虑地下室结构嵌固状态的影响、如何合理简化形成符合工程实际的计算模型,并进行高效率、高精度的计算是广大设计人员特别关注的一个重要问题。针对随意选择的建筑结构的地下室侧向刚度与上部结构楼层侧向刚度比对地下室嵌固作用进行分析,用以验证高规中关于地下室顶板作为嵌固端条文的合理性。

THE INFLUENCE OF LATERAL STIFFNESS OF IRREGULARITY STRUCTURES IN FIXED BASEMENT

For the basement of tall,Superhigh and complex multi-layer structure,with basements the following issues are the most important ones for designers in analysis and design of these kinds of buildings,such as how to consider the effect of partial fixing in basement,and how to rationally simplify the computation model of the structures. Aiming at verify the reasonability of basement roof as partial fixing in high structure standard,this article analysed the lateral structure chosen at random in the basement of the lateral stiffness and stiffness ratio of superstructure floor basement.
