摘要

为了减轻作为建筑围护结构时混凝土夹心板因承受内外叶温度差作用而导致墙体开裂或破坏的情况，对其在温度作用下的内力和变形进行研究。将混凝土夹心板内外叶连接件匀质化，并假设内外叶混凝土只产生弯曲变形且内外叶的弯曲曲率不同，推导出混凝土夹心板的界面应力的解析解，从而得到夹心板内外叶最不利截面位置及其内力和挠度的理论计算公式，并利用有限元软件ABAQUS对理论公式进行验证。结果表明：理论公式与有限元分析结果吻合较好，且部分组合混凝土夹心板内外叶的跨中最不利截面内力与连接件刚度无关，跨中最大挠度随连接件刚度增大而增大，但增幅很小。

Abstract

In order to reduce the crack or damage of the wall caused by the temperature difference between the inner and outer blades when the concrete sandwich slab is used as building envelope

the internal force and deformation of the concrete sandwich slab under the temperature action are studied. The internal and external blade connectors of concrete sandwich slab were homogenized

and the analytical solution of interfacial stress of concrete sandwich slab was deduced

assuming that the internal and external blade only produced bending deformation and the bending curvature of the internal and external blade were different. Thus

the theoretical calculation formula of the position of the most disadvantageous section of internal and external blade of concrete sandwich slab

as well as the internal force and deflection of internal and external blade were obtained

and the theoretical formulas were verified by the finite element software ABAQUS. The results show that the theoretical formula is in good agreement with the finite element analysis results

the internal forces of the most unfavorable section in mid-span of the inner and outer blades of partial composite concrete sandwich slabs have nothing to do with the stiffness of the connectors

and the maximum mid-span deflection increases with the stiffness of the connectors

but the increase is small.
