Flexural-Torsional Buckling of H-Beams with Corrugated Webs
To analyze the flexural and torsional buckling of H-beams with corrugated webs, the stress characteristics were compared with beams with plat webs firstly, then, the previous methods calculating warping constant of the H-beams with corrugated webs was discussed. Based on such works, a new calculation method was put forward. This method is simple in shape, by which the warping constant can be calculated easily. To test the accuracy of the method, plenty of numerical simulation models of beams under uniform bending was used to compare the difference between each method. The results proved that the method in this paper was successful and convenient.
