【摘要】 以钢筋型和型钢型复合墙板为基本单元的墙梁柱复合结构体系替代砌体结构在中低层建筑中的应用有利于环保和可持续发展。该文用ANSYS在试验结果验证的基础上对钢筋型混凝土墙板的轴向受力性能进行了有限元分析。结果表明,该墙板具有比砌体结构更高的竖向承载力。通过对影响墙板承载力和变形性能的主要参数如偏心距、肋宽和配筋率的分析表明,荷载偏心距和配筋率对墙板的极限承载力的影响最为明显,而板面混凝土厚度和肋宽可按最小构造要求处理。据此可对这类墙板进行合理的设计。更多还原

【Abstract】 The wall-beam-column combined structural system overcomes the disadvantages of masonry structures and can be applied to low or moderalely high buildings. The structure includes two kinds of wallboards, concrete-reinforced wallboard and concrete wallboard with profiled bars. The behavior of concrete-reinforced sandwich wallboard under axially compressed loading was analyzed using the software ANSYS. The results and experimental data show that the ultimate loading capacity of this wallboard is greater than that of a wall made of bricks of the same size. The load eccentricity and steel content in the wallboard have more influence on the ultimate loading capacity of the wallboard than the concrete thickness on the wallboard surface and the rib size. The rib size and surface concrete thickness can be quite small. These results can be used for accurate design of this kind of wallboard.更多还原
