罕遇地震下带转换层的高层剪力墙结构损伤分析

Damage Analysis of a High Rise Shear-wall Structure with Transfer Story Subjected to Rare Earthquake

为研究罕遇地震作用下某带转换层的高层钢筋混凝土剪力墙结构的抗震性能,应用有限元软件ABAQUS,结构中的钢筋和混凝土采用弹塑性本构模型,较为深入地分析了该结构在罕遇地震作用下框架、剪力墙和楼板的损伤演化过程。分析结果表明,在罕遇地震作用下,转换梁及其附近剪力墙、楼板出现一定程度的损伤,框架构件损伤程度较小。

In order to study the seismic behavior of a high rise shear-wall structure with transfer story subjected to rare earthquake, the FEM package ABAQUS was adopted to analyze damage evolution process of frame, shear wall and floor slab in this structure, where the damaged plasticity constitutive model of reinforcement and concrete is included. The analytical results show that the transfer beam, floor slab and shear wall appear a certain degree damage, but minor damage is found in frame members.
