(中国建筑科学研究院PKPM CAD工程部 北京 100013)[提要] 在简要评述薄壁杆件理论的基础上,用薄壁杆件理论分析了钢筋砼剪力墙存在的问题,并以几个算例定量地说明了其模型化误差的大小。
[关键词] 高层建筑 剪力墙 有限元分析 薄壁杆件 误差The theory of thin-wall element is briefly reviewed. The problems caused by analyzing the shear walls
with the theory of thin-wall element.are discussed. At last, some examples are given to show the errors
brought about by the simplification of the shear walls into thin-wall elements.
Keywords: tall building; shear wall; finite element; analysis model; error
