摘要
为研究双层波纹钢板混凝土组合剪力墙抗震性能,借鉴无屈曲波纹钢板剪力墙的模型简化方法,将双层波纹钢板混凝土组合剪力墙板简化为等效交叉支撑,并通过有限元软件将双层波纹钢板混凝土组合剪力墙精细模型与简化后的模型进行了对比,验证了简化模型的准确性。参考现有高层建筑的平面布置方式分别建立了双层波纹钢板混凝土组合剪力墙高层精细实体模型和简化模型,并在X、Y两个方向分别加载地震波做动力荷载下的有限元模拟,对比整体结构关键指标,探究简化模型在动力荷载下是否适用于结构的抗震性能分析。结果表明,该简化模型可以用于工程中代替精细模型高效地进行模拟分析,且对结构的关键性指标影响不大,对于层间位移等关键指标计算合理。
In order to study the seismic performance of corrugated double-skin composite shear wall,based on the simplified model of non buckling corrugated steel plate shear wall,the corrugated double-skin composite shear wall is simplified to equivalent cross support.And through finite element software,the fine model of double-skin composite shear wall is compared with the simplified model,which verifies the accuracy of the simplified model.Referring to the layout of the existing high-rise buildings,the high-rise fine solid model and simplified model of corrugated double-skin composite shear wall were established respectively,and seismic waves were loaded in the x and y directions respectively to compare the key indicators of the overall structure and to explore whether the simplified model is suitable for seismic performance analysis.The results show that the simplified model can be used to replace the fine model for efficient simulation analysis in engineering,and it has little effect on the key indicators of the structure.
