[提要]  被托換的剪力墻（或柱）不在轉(zhuǎn)換梁的中軸線上，這時(shí)的轉(zhuǎn)換梁就是偏心轉(zhuǎn)換梁。利用通用有限元程序ALGOR中的三維塊體線彈性單元，對(duì)三種類型的偏心轉(zhuǎn)換梁分別進(jìn)行實(shí)例分析；并將ALGOR的應(yīng)力結(jié)果積分為內(nèi)力（扭矩、軸力、剪力和彎矩），繪制成內(nèi)力圖。通過(guò)分析偏心轉(zhuǎn)換梁的內(nèi)力，得出了一些轉(zhuǎn)換梁的特點(diǎn)，包括偏心轉(zhuǎn)換梁的扭矩變化規(guī)律、軸力對(duì)轉(zhuǎn)換梁的影響等。

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.
Keywords:  excentral transfer beam; finite element analysis; internal force diagrams; torsion
