| 摘 要： | 为了分析钢筋混凝土曲线箱梁的非线性力学性能,提出了钢筋混凝土曲线箱梁双重非线性耦合方法.该方法采用虚拟层合板壳单元,综合考虑曲线箱梁的材料非线性和几何非线性,得到了应力-应变、位移-应变的非线性关系.在中心荷栽作用下,以一简支钢筋混凝土曲线箱梁为例加以验证.结果表明:该方法所得结果与实验值吻合较好,能够有效地反映该类结构的受力性能和破坏过程.

| Abstract: | This paper proposes a method of double nonlinear coupling analysis to treat the nonlinear mechanical performance of reinforced concrete curve box girder.The method involves the use of Virtual Laminated Plate-Shell Element to analysis of material and geometrical nonlinear properties of curve box girder and the nonlinear relations of stress-strain and strain-displacement.The use of the method to the analysis of a simply supported concrete curve box girder,subjected to the centered load,proves that the method,... |
