钢骨转换梁结构受力性能的有限元分析

Finite Element Analysis on Steel Reinforced Concrete Transfer Beam

结合某高层建筑的钢骨混凝土转换梁设计,利用有限元分析了钢骨混凝土转换梁结构与上部剪力墙共同作用下的应力、位移分布。通过建立三维块体弹性单元,利用ANSYS8.0分析软件按照特殊路径计算了该建筑中的钢骨转换梁结构体系的内力与挠度,得到的模拟数值结果与实际工程计算结果吻合良好,并通过对数值结果的分析总结了钢骨混凝土转换梁受力性能的特点。本文采用的分析方法可为钢骨混凝土转换梁与上部剪力墙共同作用的理论研究提供参考。

According to a highrise building with the transfer story in Xinxiang City,it is concerned with stress and displacement analysis of the steel reinforced concrete transfer beam by use of FEM.It indicates that the calculating results both by the proposed FEM and engineering design method are approximate.Features of stress state of the steel reinforced concrete transfer beam are summarized.An effective analysis method for the transfer beam structure is offered.
