Effect of Stiffeners on Shear Lag in Steel Box Girders

Al-Khawarizmi Engineering Journal, 2012
This paper studies the effects of stiffeners on shear lag in steel box girders with stiffened flanges. A three-dimensional linear finite element analysis using STAAD.Pro V8i program has been employed to evaluate and determine the actual top flange stress
