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。
The structure of a 8 degree zone overrun high-rise structure is a frame-core tube structure. By analyzing the overall index and seismic performance of the structure after the maximum displacement angle limit of the maximum layer is relaxed due to the earthquake, the feasibility is demonstrated. The analysis shows that When the displacement angle limit is relaxed, it has a certain influence on the overall structure index, but it has little effect on the seismic performance of the structure. The maximum displacement angle limit of the structure is a macroscopic quantity, and has no direct relation with the seismic performance level of the structure.
