摘要
被托换的剪力墙 (或柱 )不在转换梁的中轴线上 ,这时的转换梁就是偏心转换梁。利用通用有限元程序ALGOR中的三维块体线弹性单元 ,对三种类型的偏心转换梁分别进行实例分析 ;并将ALGOR的应力结果积分为内力 (扭矩、轴力、剪力和弯矩 ) ,绘制成内力图。通过分析偏心转换梁的内力 ,得出了一些转换梁的特点 ,包括偏心转换梁的扭矩变化规律。
The beam is named as accentual transfer beam if the translated shear wall(or the column) isn't on the axle of the transfer beam.The author analyzed excentral translated beams of three different types by the finite element analysis of ALGOR.Stress resulted from ALGOR is intergrated into internal force(torsion,axial force,shearing force and bending moment),and internal force diagrams are drawn.Some characteristics of excentral transfer beam are obtained from the analysis results,specialy about torsion and axial force.
