Abstract

Girders with corrugated webs have multiple desired characteristics, including high shear strength and stability, lightweight, extended fatigue life, and reduced construction cost. As a result, they have been used to replace conventional flat web girders in newly completed structures. Two plates (skins) and one center corrugated plate are used to make a core web with a corrugated plate. The beneficial features of the corrugated web are increased by employing the corrugated core web rather than just the corrugated web. Several experimental experiments were carried out in this work to evaluate the behavior of steel plate girders with corrugated core webs under shear force. Nine simply supported girders were built and tested under mid-span concentrated stresses. Trapezoidal corrugated steel web was used in this study. Three shear span-to-depth ratios (a/d) of 1.0, 1,83, and 2.5 were examined. This study also looked at the influence of core thickness on girder performance. Two core thicknesses were examined (30 and 60 mm), and three standard flat web girders were built and tested for comparison. The tested beams' maximum displacement, ultimate load, and load-deflection diagrams were recorded and compared. Among the conclusions drawn in this study that the ultimate load capacities at a/d of 2.5 and 1.833 were lower by about 16% to 29 %, respectively, compared to the corresponding values at a/d =1.0. The core thickness was also determined to play a significant role in the behavior of the tested girders.
