摘　　要：基于薄板的稳定问题,研究砌体墙板的高厚比限值.将匀质化后的砌体墙看成正交各向异性薄板,运用板理论研究砌体墙板的力学性能,推导出匀质化墙板的压曲临界载荷计算公式,进而建立了墙板高厚比限值的计算公式,并将其计算值与现行规范允许值进行比较,验证了公式的适用性.结果表明,借助弹性力学中板的稳定问题来研究匀质化后的砌体墙板的稳定性是可行的.Based on plate stability,the height-to-thickness ratio limit of masonry wall panels was studied.The homogenized masonry wall was regarded as an orthotropic thin plate,and the mechanical properties of the masonry wall panel were studied using the plate theory,and the calculation formula of the buckling critical load of the homogenized wall panel was derived.Furthermore,a calculation formula for the limit value of the wallboard height-to-thickness ratio was established,and the calculated value was compared with the allowable value of the current code to verify the applicability of the formula.The results showed that it is feasible to study the stability of homogenized masonry wall panels with the help of the stability of the slab in elastic mechanics.
