某高层剪力墙结构抗震设计与分析

Seismic design and analysis of a shear wall structure

剪力墙结构是高层建筑中应用较为广泛的一种结构形式,但其抗震性能研究和分析还处于发展阶段,为进一步研究分析其抗震性能,以一个地上26层、地下2层、A级高度的剪力墙结构实际工程为研究对象,从结构体系、结构选型与布置、计算分析等方面介绍高层剪力墙结构的设计依据和实施过程,并通过拟定合理的性能目标,基于抗震性能的设计方法,采用了有限元计算分析软件对此结构进行了小震反应谱分析、多遇地震弹性时程分析、大震作用下的静力弹塑性推覆分析和动力弹塑性时程分析。研究分析表明,选取的结构体系、结构性能均满足抗震设防目标的要求,同时也为同抗震设防烈度区、同类结构的抗震分析提供参考和借鉴。

The structure of shear wall is widely used in high-rise building,but research and analysis of its seismic performance is still in the stage of development. For further research and analysis its seismic performance,the actual project of the shear wall structure with 26 floors,2 floors above ground,and a class a height was studied. The basis design and the implementation process of high-rise shear wall structure were introduced,in terms of structural system,selection of structural type and layout,calculation and analysis. The finite calculation analysis software was used to analysis this structure of the small earthquake response spectrum analysis,elastic seismic history analysis of Pushover analysis and dynamic elastic plastic time history analysis of earthquake under the action of static elastic plasticity. Research and analysis show that the selections of structure system,structures are both satisfy the seismic fortification goal requirement.At the same time,as the with the region of seismic fortification intensity,seismic analysis of similar structure provide reference.
