T形截面SRC异形柱正截面受力性能的分析

Analysis on Mechanical Properties of Normal Section of SRC Special-shaped Columns with T-shaped Section

为了研究SRC异形柱正截面的受力性能,利用自己编制的型钢混凝土异形柱正截面承载力电算程序,通过计算得到了混凝土强度、加载角、配钢率和轴压比变化时,T形截面SRC异形柱正截面受力性能的N-M和Mx-My相关曲线。通过对相关曲线及其受力机理的分析,得到了四种设计参数变化时,T形截面SRC异形柱正截面受力性能的变化规律。

In order to study the normal section mechanical properties of SRC special-shaped columns, N-M interaction curves and Mx-My interaction curves of the normal section of SRC special-shaped columns with T-shaped section are obtained through calculating by the computer programs established by our own when changing concrete strength, loading angle, steel ratio and axial compression ratio. Through the analysis on the interaction curves and load- bearing mechanism, the change rules of the mechanical properties of normal section of SRC special-shaped columns with T-shaped section are summarized when four design parameters changed.
