钢骨混凝土转换梁结构的数值模拟与分析

Numerical Simulation on Steel Reinforced Concrete Transfer-Beam of High-Building

以有限元理论为基础,对在工程实际荷载作用下的某高层建筑中的钢骨混凝土转换梁结构体系进行非线性有限元计算分析。利用ANSYS分析软件对钢骨转换梁沿梁顶、钢骨上下翼缘顶、翼缘底、钢骨中线及梁底等为路径进行应力和位移的分析,得到了转换梁的基本应力和位移状态规律。数值模拟表明,转换梁作为结构体系中的偏心受拉构件,与上部剪力墙之间存在共同作用。本研究结果为以后钢骨混凝土转换梁结构体系的设计和研究提供了理论基础。

This paper is concerned with stress and displacement analysis of the steel reinforced concrete transfer beam by use of FEM. 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 available.
