摘　　要：为了提出一种多腔钢板混凝土组合剪力墙,研究其在压弯状态下的破坏模式、破坏机理、承载能力和变形能力。利用ABAQUS有限元软件建立多腔钢板混凝土组合剪力墙模型,模拟剪力墙受力情况,并用试验的方法对比验证有限元模拟分析的有效性。研究构件的轴压比、混凝土强度等级和钢板厚度等参数的变化对多腔钢板混凝土组合剪力墙的压弯性能的影响。试验和模拟发现,新型多腔钢板混凝土组合剪力墙有较好的承载能力和变形能力,不同参数对剪力墙压弯性能有不同程度的影响。其中钢板厚度对剪力墙压弯性能的影响最大,随着钢板厚度的增加,试件承载能力、变形能力大幅上升。In order to put forward a kind of multi-partition steel-concrete composite shear wall,its failure mode,failure mechanism,bearing capacity and deformation capacity under compression and bending condition were studied. The force of the multi-partition steel-concrete composite shear wall softuare were simulated by the ABAQUS ,and the effectiveness of the finite element simulation was proved by the experimental results.The effect of different parameters on the shear wall bending performance was studied,for instance the axial load ratio,the concrete strength grade and the built-in steel sheet thickness.The experimental and simulation results show that the new multi-partition steel-concrete composite shear wall has good bearing capacity and deformability,and different parameters have different degrees of effects on the bending performance of the shear wall.Among them,the thickness of the steel plate has the greatest influence on the compression behavior of the shear wall.With the increase of the thickness of the steel plate,the bearing capacity and deformability of the test piece increase sharply.
