基于欧标的混凝土叠合板结合面设计

Design of Interface of Concrete Composite Slab Based on European Standard

目前国内规范对混凝土叠合板结合面的设计只有一些构造的规定,无具体验算内容和计算方法,本文以中国规范GB 50010-2010、JTS 167-1-2010、欧标规范EN 1992-1-1:2004为基础,给出了结合面的不同构造、计算内容和方法,并通过案例给出不同结构结合面的抗剪计算结果,表明结合面的抗剪承载力与结合面构造、叠合板的厚度、混凝土强度以及抗剪钢筋等有关,不是所有叠合板都要设置凹凸齿。

By now,the regulations specified in Chinese Standard involve in the structure design of the interface of concrete composite slabs,but the related calculation detail and methods are not available.In the case,different structure interfaces,the related calculation detail and methods are produced by referring to Chinese standard GB 50010-2010,JTS 167-1-2010 and European standard EN 1992-1-1:2004.Anti-shear checking results of different structure interfaces are given through engineering practice.the research shows that the shear bearing capacity of the interface is affected by the structure of interface,the thickness of composite slab,concrete strength and shear reinforcement etc.It is unnecessary to set concave and convex combs on each of composite slabs.
