摘要

为研究新型闭口型压型钢板Econdek65-675组合板的破坏、挠曲、端部滑移特性及纵向承载能力，根据欧洲规范对4对18块组合板进行试验而获得相关系数m

k。制作的18个试件分别为115 mm、150 mm、200 mm 3种厚度3组，每组由3块短板与3块长板组成。试验结果发现3组试件都发生明显的端部滑移，呈现过早的纵向剪切破坏。将试验结果与欧洲规范和美国规范进行对比，结果表明欧洲规范更为准确。同时，给出了该种组合板纵向承载力计算公式及相关曲线，并与类似的其他组合板进行对比，结果显示Econdek65-675组合板具有较可靠的组合效率。

Abstract

The shear bond behavior of the flat-type composite deck slab

Econdek65-675 is investigated primarily. Based on the Euro code 4

the relevant value

m-k

is achieved based on the test of 18 composite slab specimens. According to the thickness which is 115 mm

150 mm and 200 mm respectively

these 18 specimens were divided into three groups with two sets in each group. One set was tested for shorter shear span loading and the other one was set for longer shear span loading. It is shown that the Euro code 4 is more accurate than the American code. Meanwhile

the calculation formula of longitudinal shear resistance of the composite slab as well as its relevant curve is presented. Compared with other similar composite slabs

it is proved that Econdek65-675 possesses reliable composite efficiency.
