摘　　要：采用有限元法对普钢结构与轻钢结构组合的墙体在竖向荷载作用下的承载力进行分析。结果表明,在该组合墙体中,由轻钢承受竖向荷载。当增大墙体高度时,墙架柱的轴向承载力降低;当墙架柱间距由600mm增大到1200mm时,轴向承载力略有提高。分析了冷弯薄壁型钢在组合墙体中的承载力。Finite element method（FEM）is adopted to study the bearing capacity of the the light steel and ordinary steel mixed wall under vertical load.The results show that the light steel to withstand vertical loads by combination wall.When the wall height increases,the axial bearing capacity of stud reduces.When the studs spacing increase from 600 mm to 1 200 mm,the bearing capacity increases slightly.The bearing capacity of the cold-formed thin-walled steel which is used in combination wall.
