NUMERICAL INVESTIGATION OF PLATE GIRDER HAVING CORE WEB WITH ZIGZAG CORRUGATED PANEL.

Corrugated steel flat plates have a number of benefits over conventional steel flat plates, including better buckling strength, a greater load capacity, a longer fatigue life, and cheaper construction costs. Corrugated plates have thus been used in a variety of civil engineering projects, including bridges, industrial structures, and steel coupling beams. To further enhance these properties, the web can be constructed as a core composed of two outside flat plates and a middle-corrugated panel. In this research, finite element software (ABAQUS 2017) was used to examine the effectiveness of steel plate girders containing various web types (flat plate, zigzagly corrugated plate, and core web with zigzagly corrugated panel). A large number of simply supported beam specimens were simulated and investigated under a three-point load in order to determine how the type of web affects the performance of girders under shear and flexural loadings. Three shear span-to-depth ratios (a/d) of 1.0, 1.83, and 2.5 were examined. Corrugation depth's impact on girder performance was also explored. The results of the study demonstrated that replacing flat plate web with corrugated plate having a zigzag shape improved the performance of the girders in regards to ultimate load and ductility. Additionally, when a core web was utilized, the performance of the girders was further improved. When compared to a steel girder with a flat web, the ultimate loads for girders with a core web and girders that only consisted of a corrugated plate web increased by 47% and 21%, respectively.
