This is a follow-up investigation to the study of I-girders having circular corrugated webs, in which the previous study focused on the behavior of these girders under vertical loads by Swelem et al. (2022), whereas this work presents predicted formulas to estimate the moment capacity of these girders subjected to vertical or horizontal loads. Moreover the performance of I-girders that have circular corrugated webs subjected to horizontal loads and uniform vertical loads is investigated. In order to study the out-of-plane bending stiffness, a numerical study is carried out using ABAQUS software. The effect of different geometrical factors on the behavior of this type of girders is investigated using a parametric approach. According to the results, the depth of the corrugation, the width and thickness of the flange, the height of the web and girder span all have a substantial impact on the moment capacity of this type of girders. These results are compared with the results of I-girders that have flat webs. The moment capacity of I-girders with circular corrugated web is higher than those of I-girders with flat web, based on these comparisons. Based on the parametric study results, formulas are proposed in order to predict the moment capacity of the I-girder with corrugated web. Theses formulas are verified using finite element study and the results shows a good agreement.
