摘要: 基于双向偏压作用下钢筋混凝土异形截面构件的材料非线性和几何非线性,提出一种新的简便可行的截面积分分析方法,由此推导出异形截面构件的割线、切线刚度计算公式。用该法对在双向偏压作用下钢筋混凝土异形截面构件进行了全过程非线性分析,分析结果与试验数据吻合较好。Abstract: A new and simplified numerical integration method of sections is suggested, and the secant stiffness and tangent stiffness calculation simple formulation of reinforced concrete members under bieccentric compression is derived, based on nonlinear behavior of materials and geometry. Using this method, nonlinear analysis of some reinforced concrete members under bieccentric compression are taken by tracing full path.The theoretical results correspond well with experimental data.
