摘　　要：为研究陶粒混凝土钢板组合剪力墙的受力性能,采用OpenSEES有限元软件建立了陶粒混凝土钢板组合剪力墙的计算模型,并对比试验数据验证了模型的准确性;通过数值模拟,分析了轴压比、剪跨比、截面宽厚比及钢板厚度对陶粒混凝土钢板组合剪力墙受力性能的影响。结果表明:当轴压比小于0.4时,组合剪力墙承载力随轴压比增大而升高;随着剪跨比增加,承载力近线性降低,剪跨比小于2时,延性随剪跨比增大而提高;随着截面宽厚比降低,承载力线性提升;钢板厚度增大可以显著提高墙体水平承载力,端部方钢管的钢板厚度增加对水平承载力提高作用更为明显。In order to study the mechanical performance of ceramsite concrete steel plate composite shear wall,the calculation model of ceramsite concrete steel plate composite shear wall was established by using OPENSEES finite element software,and the accuracy of the model was verified by comparing the experimental data.Through numerical simulation,the influence of axial compression ratio,shear span ratio,section width thickness ratio and steel plate thickness on the mechanical performance of ceramsite concrete steel plate composite shear wall was analyzed.The results show that:when the axial compression ratio is less than 0.4,the bearing capacity of the composite shear wall increases with the increase of the axial compression ratio;with the increase of the shear span ratio,the bearing capacity decreases linearly;when the shear span ratio is less than 2,the ductility increases with the increase of the shear span ratio;with the decrease of the section width thickness ratio,the bearing capacity increases linearly;with the increase of the steel plate thickness,the horizontal bearing capacity of the wall can be significantly improved.The increase of steel plate thickness of end square steel tube has more obvious effect on the improvement of horizontal bearing capacity.
