钢框架-支撑结构在高强度地震烈度下的反应分析

Analysis of Steel Braced Frame Structure Response Encountered Higher Seismic Intensity

结构可能遭遇高于其设防烈度的地震,在这种情况下结构会有怎样的反应成为土木工程师关注的问题。为解决这一问题,分析了一个钢框架-支撑结构在遭遇高于其地震设防烈度的地震作用下的结构反应,结果表明:钢框架-支撑结构的层间侧移、顶点位移、框架梁的抗弯强度、抗剪强度、构件的稳定等均仍能满足设计要求,钢框架结构具有良好的抗震性能。

Structure may encounter higher degree earthquake than seismic fortification intensity, in this case how the structure reacts will be a concerned problem for civil engineers. In order to solve the problem, this paper analyzes the response of a steel braced flame structure when facing higher degree earthquake than the seismic fortification intensity. The result shows that the lateral sway between layers, vertex displacement, the bending and shear strength of the frame beams and the stability of the components still meet the design requirements, and steel frame structure has good seismic performance.
