|
摘要
目的研究型钢混凝土异形柱截面承载力的计算方法.方法基于平截面假设,推导出用于双向偏压荷载作用下型钢混凝土异形柱正截面分析的刚度矩阵简便表达式.采用简便公式计算截面型钢和混凝土的刚度.利用弧长法求解非线性方程,能够较好地跟踪截面分析的下降段,编制了相应的数值分析程序.结果对型钢混凝土异形柱正截面进行全过程数值分析,理论计算结果与现有文献试验结果进行比较,二者吻合较好,表明笔者方法可行.型钢混凝土异形柱正截面承载力比普通钢筋混凝土异形柱正截面承载力好.结论此方法可用于型钢混凝土异形柱正截面的承载力计算及力学性能分析.
The paper presents an experimental research on the calculating method of the bearing capacity of normal cross-section,for steel reinforced concrete(SRC)irregularly-shaped columns.Based on plane assumption,the simple tangent stiffness matrix formulation of a cross-section is gained,for SRC irregularly-shaped columns under Bi-eccentric Bending and Compression.The simple tangent stiffness matrix formulation is used to calculate the stiffness of shaped steel and concrete.The arc-length is used to solve nonlinear equations set in order to trace the down part of the curve.Then the numerical analysis program is developed.Some cross-sections of SRC irregularly-shaped columns are traced in full load path;and the theoretical results correspond very well with other existing experimental data.This shows that the method in this paper is feasible.The normal cross-section bearing capacity of SRC irregularly-shaped columns is larger than that of RC irregularly-shaped columns.The conclusion is that the calculating method may be used to calculate the bearing capacity and analyse the mechanical performance for SRC irregularly-shaped columns.
