建筑物结构加层中“鞭梢效应”的影响

WHIPPING EFFECT ON BUILDING'S STOREY-ADDITION

多高层混凝土结构的加层设计与抗震分析,是多高层混凝土结构加层工程中的重中之重。其中涉及鞭梢效应的影响,加层方案的选择,抗侧力结构对加层结构的影响,地震烈度对结构的影响以及不同加层层数的设计等多方面因素,本章针对建筑物加层中鞭梢效应的影响进行讨论,根据对比分析分别归纳出鞭梢效应对于加层结构设计的影响关系,用于对加层的选型和加层的设计提供一些参考。

The design and seismic analysis of adding storey in high-rise concrete building is the most important in the storey-adding construction. It covers whipping effect,option of storey-adding scheme,lateral resisting structure's effect on adding-storey,impact of seismic intensity,design of adding-storey for different number of floors etc. In this paper,the whipping effect on building's storey-addition is discussed. The whipping effect on the design of addingstorey is summarized based on comparative analysis,which provides reference for design and selecting types of adding-storey.
