摘要
为了得到一高50m的钢筋混凝土空心桥墩极限承载力,基于ANSYS软件,采用8节点等参单元SOLID65,考虑几何非线性、材料非线性以及结构的初始缺陷等因素,对桥墩进行了极限承载力全过程分析,得到了结构的极限荷载、荷载-变形曲线及裂缝的分布。分析结果表明,高桥墩的非线性因素明显,在计算中应充分考虑。
To obtain ultimate bearing capacity of a 50m-tall reinforced concrete hollow pier,nonlinear numerical simulation on the RC hollow pier using ANSYS program was carried out by considering geometrical nonlinear,nonlinear material and initial geometrical defect,and 8-node isoperimetric element was adopted.The ultimate load,load-displacement curve and cracks distribution were obtained.The results show that nonlinear effects are remarkable that cannot be neglected in design.
