框架结构梁端截面有效翼缘宽度的有限元分析
|
摘要
采用ABAQUS软件中非线性有限元分析常用实体单元C3D8R模拟混凝土框架及现浇板,杆单元T3D2模拟钢筋,建立了钢筋混凝土框架结构非线性有限元模型,分析了梁端截面有效翼缘宽度在弹性阶段和弹塑性阶段的取值情况,提出了有效翼缘宽度bf′的计算方法。
The reinforced concrete frame and slab were simulated by the common soild element C3D8R in the non-linear finite element analysis model of the ABAQUS software,the reinforcement was simulated by the truss element T3D2,establishing the non-linear finite element models of RC frame structure.Analyzes the value status of the effective flange width of the end-plate section in the elastic stage and the elastic-plastic stage,and points out the calculation methods of the effective flange width bf′.
