Analysis of Pure Torsional Constant of I-Girder with Corrugated Webs

Resistance to lateral torsional buckling of steel I-girder (open section) is a very important design requirement. But, most studies of steel I-girder with corrugated webs were invested in shear behavior. Untill now, most studies about Lateral torsional buckling of I-girder with corrugated webs have been based on Lindner.J`s study (Lateral torsional buckling of beamswith trapezoidally corrugated webs,1990). the study includes that the pure torsional constant of I-girder with corrugated webs <TEX>$J_{cor}$</TEX> doesn`t different from that of I-girder with flat webs. This paper pesents pure torsional constant of I-girder with corrugated webs by using finite element anaysis.
