中文摘要：
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.
英文摘要：
The composite wall slabs are composed of the lattice type multi-ribbed of reinforced concrete and lightweight block.Stability of the wall slab is an important role to bearing capeicity of the slab under axial compression load,in which the ribs and blocks coupling.Based on structural properties of the composite wall slab,the calculating element of composite wall slab is shown,the element rigidity of the wall slab are presented.The explicit formulate for the displacement of the slab in a distortional buckling mode are derived,the critical compression stress is presented.Finally by the example demonstrated,the thickness of the composite wall,the sectional dimension and the spacing of the lattice,and the modulus of block axe clear effects to the critical compression stress of composite wall.
