摘要:
为了研究不同含圆钢率对新型可适用于高层建筑的装配式内置双钢套管混凝土组合剪力墙抗震性能的影响,采用有限元软件ABAQUS对该组合剪力墙进行拟合分析?依据组合剪力墙试验数据等参数建立SW1~SW4?SW6模型,进行水平单推加载并与试验结果骨架曲线进行对比?有限元模拟所得位移-荷载曲线和试验值具有较好的吻合度,极限承载力误差不超过10%?对比验证有限元模型的合理性获得与试验一致性结论?依据已验证有限元模型建立5个不同含圆钢率的组合剪力墙模型进行单推加载分析?结果表明:组合剪力墙的承载力随含圆钢率增加而呈线性提高,位移延性随含圆钢率的增加而提高,在6.35左右达到峰值后开始下降,分析结果为后续该组合剪力墙的优化,应用实际工程提供参考?
Abstract:
In order to study the influence of different round steel ratios on the seismic performance of a new type of prefabricated built-in double-steel casing concrete composite shear wall,which is suitable for high-rise buildings, finite element software ABAQUS is used in this paper to conduct fitting analysis for the composite shear wall. SW1~SW4 and SW6 models were established based on the combined shear wall test data and other parameters, and the horizontal single push loading was carried out and compared with the skeleton curve of the test results. The displacement-load curve obtained by the finite element simulation is in good agreement with the test value,and the error of the ultimate bearing capacity does not exceed 10%. By comparing and verifying the rationality of the finite element model,the conclusion is consistent with the test. Based on the verified finite element model,5 combined shear wall models with different round steel ratios were established for single push loading analysis. The results show that the bearing capacity of the combined shear wall increases linearly with the increase of the round steel ratio,and the displacement ductility increases with the increase of the round steel ratio,and starts to decline after reaching the peak value around 6.35. The analysis results provide reference for the subsequent optimization and application of the combined shear wall in practical projects.
