Analysis of flange impact on critical patch load of thin-walled I-girders
Abstract
A numerical analysis of the flange impact on the critical load level of thin-walled I-girders subjected to patch load. The analysis is done by forming a 3D model in Abaqus software based on the finite element method, through variation of flange to web thickness ratio. 2D numerical models of girders web as isolated plate are also created. Matching of the 2D numerical results with results of existing analytical model, is the real basis for the expected accuracy of the 3D model.
