Abstract

Abstract Corrugated steel-plate girders are used as structural elements in many applications because of their properties, cutouts are always provided in these plate elements to enable inspection and servicing. This study presents an experimental and analytical study to investigate the efficiency of a steel-plate girder with corrugated webs (GCWs) and flat webs (GFWs) having cutouts under shear loading. In this study, we investigated the influence of some important parameters on the girders’ load-bearing capacity. The experimental program was conducted on six full-scale plate girders, which have been tested under central load at mid-span. The analysis was conducted using ANSYS V20 to perform a nonlinear technique for the determination of the ultimate load of the tested girders. Finally, experimental and finite element model were used to define the ratio of increasing carrying capacity in plate girder with flat and corrugated web, having cutout under shear loading. The ultimate strength, failure mechanism, and load-deflection curves from the experimental and analytical study show that the shear capacity of the girder with corrugated web girders extends loads by 22 % compared with the flat web.

纯剪下波形腹板与平腹板钢板梁腹板开孔效率的比较

波纹钢板梁由于其优良的性能，在许多应用中被用作结构构件，在这些板构件中总是提供切口，以便进行检查和维修。本研究提出了一项实验和分析研究，以探讨具有切割的波纹腹板(GCWs)和扁平腹板(GFWs)的钢板梁在剪切荷载下的效率。在本研究中，我们研究了一些重要参数对梁的承载能力的影响。对6根全尺寸板梁进行了跨中中心荷载试验。采用ANSYS V20进行分析，采用非线性技术确定受试梁的极限荷载。最后，采用试验模型和有限元模型确定了剪切荷载作用下平腹板和波纹腹板的承载力增加比例。试验和分析结果表明，波纹腹板梁的极限强度、破坏机理和荷载-挠度曲线比扁平腹板梁的抗剪承载力提高了22%。
