高层磷石膏墙体网格式框架结构在水平荷载下,内力不以剪力为主,整体弯矩起主要控制作用。采用有限元软件PKPM,以层数为变化参数,研究水平及竖向荷载作用下整体弯矩对结构受力性能的影响。计算结果表明:整体弯曲对底层柱底倾覆弯矩影响较大,轴力基本呈线性关系增加,而对倾覆剪力的影响较小。其底部变形呈弯曲型,上部变形呈剪切型。边框架柱截面面积相等时,矩形框架柱承担轴力和剪力分别比L形大2%和15%;边框架柱截面惯性矩相等时,矩形框架柱承担轴力和剪力分别比L形大9%和18%。
The high-rise phosphogypsum wall mesh frame structure under horizontal load, the internal force is not shear-based, the overall bending moment plays a major role in the control. The finite element software PKPM is used to study the influence of the integral moment on the behavior of the structure under horizontal and vertical loads. The calculation results show that the overall bending has a great influence on the overturning moment of the bottom column, the axial force increases linearly and the impact on the overturning shear is small. The bottom of the deformation was curved, the upper deformation was sheared. When the cross-sectional area of the frame columns is equal, the rectangular frame columns bear the axial force and the shear force which are respectively 2% and 15% larger than those of the L-shaped columns. When the moment of inertia of the frame columns is equal, Big 9% and 18%.
