某高烈度区超限高层结构层间位移角限值放松可行性分析

The Feasibility Analysis of Increasing the Limit of the Displacement Angle between the Super High-rise Structures in a High Seismic Intensity Area

某8度区超限高层结构为框架-核心筒结构体系,通过分析多遇地震作用下最大层间位移角限值放松后结构的整体指标和抗震性能情况,从而论证其可行性,分析结果表明位移角限值放松后对结构整体指标有一定影响,但对结构抗震性能影响不大,结构最大层间位移角限值是宏观量,与结构的抗震性能水准之间没有直接关系。

A 8 degree area of high-rise structure for frame core tube structure system,through the analysis of the maximum allowable value of drift angle of the structure of the overall relaxed index and seismic performance,demonstrate the inter story displacement angle to relax the feasibility. The analysis results show that the displacement angle of relax,have a certain impact on the overall structure of the index, but has little effect on thc seismic performance of the structure,the maximum inter story displacement angle is the macroscopic quantity, and there is no direct relationship between the seismic performance of structure.
