[提要]  利用通用有限元程序ALGOR中的三維塊體線彈性單元，對(duì)兩條墻肢并排被支承在同一條柱上的梁式轉(zhuǎn)換進(jìn)行了實(shí)例分析。計(jì)算模式中考慮了豎向壓力、剪力和彎矩三種外力的共同作用，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），繪制成轉(zhuǎn)換梁的內(nèi)力圖。通過(guò)對(duì)轉(zhuǎn)換梁的內(nèi)力進(jìn)行分析，得出了這種轉(zhuǎn)換梁的受力特點(diǎn)，包括梁上剪力墻對(duì)轉(zhuǎn)換梁扭轉(zhuǎn)的約束，轉(zhuǎn)換梁的軸力對(duì)彎矩的影響等。

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