摘　　要：为获得轻钢轻质混凝土组合墙轴压性能,以试验模型为基础,采用ABAQUS软件建立墙体有限元模型,将数值模拟结果与试验结果对比,二者吻合较好。在此基础上,分析了含钢率、轻质混凝土强度对轻钢轻质混凝土组合墙轴压承载力的影响。结果表明随着含钢率的提高,其峰值荷载也随之提高,含钢率对组合墙体的轴压承载力及刚度有重要作用。随着泡沫混凝土强度的提高,组合墙体的刚度及轴压承载力显著提高,但延性系数有所降低。This paper studies the axial compressive performance of light steel lightweight concrete combination wall,the finite element model of which is established by ABAQUS software.The numerical simulation results are compared with the experimental results,showing a good agreement with each other.On this basis,the effectiveness of steel content and lightweight concrete strength on the axial compressive capacity of lightweight steel and lightweight concrete combination wall is analyzed.The results show that with the increase of steel content,the peak load also increases,and the steel content plays an important role in the axial compressive load capacity and stiffness of the combined wall.With the increase of foam concrete strength,the stiffness and axial compressive load capacity of the combined wall increase significantly,whereas the ductility coefficient decreases.
