摘要:
为研究钢-混凝土组合框架梁的刚度对组合框架抗震性能的影响,通过某多层钢结构工程实例,采用有限元软件ANSYS分别建立了纯钢框架、组合梁框架及其不同阻尼比下的框架计算模型,进行了纯钢框架与组合框架在不同阻尼比下的多遇地震反应谱分析及弹性时程分析。实例分析结果表明:考虑钢框架的组合作用后,结构整体自振周期变短,说明结构整体刚度变大,地震层间位移变小。虽然组合框架整体刚度的增大使地震力有所加大,但由于组合结构阻尼比接近混凝土结构阻尼比,组合框架无论是结构侧向位移还是地震力均小于纯钢框架,因此组合框架是一种良好的结构形式。
Abstract:
To study the steel-concrete composite frame rigidity, which influences the seismic performance of composite frame, authors analyzed a multi-storied steel project by two different ways, one treated the project as steel frame and the other treated it as composite frame which took the composite effect based on finite element analysis software ANSYS, to proceed the normal earthquake response spectrum analysis and elastic time-history analysis under different damping ratios of these two ways. The results which take the composite effect into account show that the natural vibration period is shorter, the rigidity of the structure is larger and the inter-story drift is smaller than the result of the other way. Although the rigidity of the structure is larger, the force of seismic is little larger. Because its damping ratios is similar with concrete structure, its drift of story and force of seismic are smaller than steel structure, and it is a good form structure.
