装配式剪力墙水平拼缝抗震性能分析

摘要

考虑装配式剪力墙水平拼缝处理对结构的安全性影响较大,采用有限元软件ABAQUS,建立了非线性精细有限元模型,说明了单元选取、材料应力应变关系的确定方法,并结合国内已有的试验数据,验证了非线性有限元模型的正确性和适用性.%If precast shear wall with reinforcements grouted in holes and spliced indirectly in horizontal connections was improper treated,the safety had great influence.Efficient and accurate FEM of ABAQUS was proposed for numerical simulation.The selection of elements types,the material stress-strain relationship and damage model were made a detailed description.Non-linear finite element model was approved with existing test.
