【提要】 采用有限元分析程序ANSYS，对剪力墙下部地基梁的三种截面和配筋各异的情况，建立了包
括剪力墙、桩和地基梁的整体模型。通过分析和比较，指出目前的有些设计思路使得该类地基梁的设计截面和配筋明显偏大。应该采用有限元非线性静力分析的手段进行该类地基梁的设计，以得到安全经济的结果。

FEM Analysis on Beams Under Shear Walls/Cao Hui，Lin Xuepeng(Faculty of Civil Engineering, Chongqing University, Chongqing 400045,China)
Abstract:With FEM software ANSYS, three models including shear walls，beams under the shear walls and piles under the beams, are built considering respectively three cases with different sectional sizes and longitudinal reinforcing bars of the beams. It is found that some of the common design ideas for such beams make the design results greatly conservative. The FEM nonlinear analysis is appropriate for the design of such beams and should be adopted to get safe and economical results.
