轴压比对宽扁梁柱节点受力性能影响的分析

Influence of Axial Compression Ratio to Mechanical Behavior of Wide Flat Beam Connection

运用ANSYS软件,对宽扁梁柱节点进行有限元分析,重点研究了轴压比对模型的承载力、梁端位移及荷载位移曲线的影响,认为合理控制轴压比在0.2 ～0.7的范围内,能使结构具有较高的承载力及较大的刚度,这就为宽扁梁在实际工程中的应用提供理论依据.

With ANSYS software, this paper makes finite element analysis on wide fiat beam connection, focusing on the bearing capaci- ty of axial compression ratio to the model and the influence of the curve of displacement at bridge end and the load displacement. The author thinks that if we reasonably control the axial compression ratio in the range of 0.2 ~ 0.7, the structure will have higher bearing capacity and larger rigidity. This provides a theoretical basis for the application of wide flat beam in practical engineering.
