单梁托四墙的梁式转换的有限元分析

FEM Analysis of Transfer Beams with Four Shear-walls Supported by a Beam

利用通用有限元程序ALGOR中的三维块体线弹性单元 ,对两条墙肢并排被支承在同一条柱上的梁式转换进行了实例分析。计算模式中考虑了竖向压力、剪力和弯矩三种外力的共同作用 ,并将ALGOR的应力结果积分为内力 (扭矩、轴力、剪力和弯矩 ) ,绘制成转换梁的内力图。通过对转换梁的内力进行分析 ,得出了这种转换梁的受力特点 ,包括梁上剪力墙对转换梁扭转的约束 。

The author discussed a transfer beam with two shearwalls supported by a column.The analysis results were obtained from the finite element analysis software of ALGOR with 3 dimensional solid element.Loading force,including vertical pressure force,shear force and bending moment is taken into account.Stress which resulted from ALGOR is integrated into internal force(torsion,axial force,shearing force and bending moment).The characteristics of the transfer beam is gotten from the analysis results for design of the structure.
