摘要

本文基于正交异性板壳有限元理论,分析了组合楼板对结构平面布置不规则的高层钢结构受力性能的影响。通过有限元分析,确定了发生平面内剪切变形时组合楼板的有效高度。结合两个工程实例,分别按弹性正交异性楼板、刚性楼板两种假定对整体结构进行水平地震作用分析。两种模型计算结果的对比分析表明,弹性正交异性板壳单元模型能更准确地分析结构的周期、内力、位移等参数。
Based on an orthotropic shell element method, the effect of composite slabs on the behavior of steel structure in tall buildings with irregular plan layout has been studied. The effective height of composite slabs with in-plane shear deformation has been suggested by the finite element analysis. Two practical tall steel buildings have been analyzed under the action of horizontal earthquakes with the orthotropic shell element hypothesis and the rigid floor hypothesis, respectively. Comparison of the results based on these two different hypotheses shows that the orthotropic shell element method can predict the behavior of whole structures more accurately.
