框架-剪力墙结构剪切-弯曲模型精确性研究

摘要

Using a 10-storey and a 12-storey frame-shear wall structure as examples, the frame part of frame-shear wall structure is simplified to a many-particle system shear column which floor quality focuse on floor, the shear wall part is simplified to a bending column of equal section considering shear deformation,then the frame-shear wall structure is simplified to a accomplished system which two parts depend on each other—"shear-bending" model. With self-programme,the elastic time history analysis of earthquake response is carried out the rationality and accuracy of the " shear-bending" model are discussed. And the results are compared with which using Midas software, the two results are basically the same.%以10层和12层框架-剪力墙结构作为算例,将框架-剪力墙结构中的框架部分简化为楼层质量集中于楼板处的多质点系剪切柱,剪力墙部分简化为考虑剪切变形的等截面弯曲柱后,将框架-剪力墙结构简化为这两个部分互相依靠的并立体系-“剪切-弯曲”模型.利用自编程序进行地震响应弹塑性时程分析,讨论“剪切-弯曲”模型的合理性和精确性.与利用Midas软件的分析结果进行比较,两者结果基本一致.
