格构式密肋轻质砌块组合墙板是由格构式钢筋混凝土密肋和轻质砌块组成的组合式墙板.在轴心压力荷载作用下,该墙板的密肋和肋间的轻骨料砌块共同承担荷载,其的稳定性对于墙体结构的承载性能的发挥起到至关重要的作用.基于该墙板的边界条件,确定了墙板的计算单元.通过单元内力平衡方程,给出了该墙板单元等效刚度方程.基于挠度控制方程,确定组合墙板的临界压应力,分析了影响其稳定主要因素.并算例分析表明:格构式密肋轻质砌块组合墙板的厚度,密肋截面尺寸和间距,砌块弹性模量对轴心受压的墙板临界压应力有明显的影响.
Grid-structured light-weight lightweight block combined wall panels are modular wall panels composed of lattice reinforced reinforced concrete lightweight ribs and lightweight blocks.Under the axial pressure load, the ribs and intercostal space of the wallboard Of the light-weight building blocks bear the load together, and its stability plays a crucial role in the bearing capacity of the wall structure.Based on the boundary conditions of the wallboard, the calculation unit of the wallboard is determined.The internal force The equilibrium equations are given and the equivalent stiffness equations of the panel elements are given. Based on the deflection control equations, the critical compressive stress of the composite panel is determined and the main factors affecting its stability are analyzed. The thickness of block combined wallboard, the section size and spacing of dense ribs, the elastic modulus of block have a significant influence on the critical compressive stress of the wallboard under axial compression.
