组合钢板剪力墙结构动力时程分析
|
摘要
利用Sap2000有限元分析软件,以济南某医院医职配套楼为实例,在EI-Centro NS波作用下对建筑结构物进行动力时程分析,研究组合钢板剪力墙的综合性能。有限元模型采用三维空间模型,受双向地震作用,采用组合钢板剪力墙体系,并与钢筋混凝土和钢板剪力墙体系进行对比。结果表明,组合钢板墙具有侧向刚度大,变形能力强的特点,其综合性能优于传统剪力墙。
Based on a hospital building in Jinan,the dynamic time-history analysis was carried out under the action of EI-Centro NS waves by use of Sap2000,and the overall performance of composite steel shear walls was investigated. A three-dimensional FEM model under bidirectional ground motion was established to study the composite steel shear wall structure,and the results were compared with that of reinforced concrete shear walls and steel shear walls. The results indicate that the composite steel shear wall has the advantages of high lateral stiffness and well deformation ability,and its overall performance is superior to that of traditional shear walls.
