Effect of Imperfection on Shear Behaviour of Hybrid Plate Girder
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 5
Abstract
The influence of initial imperfection of plates on the shear resistance of hybrid plate girder fabricated using slender plate elements is studied. Nonlinear finite element analysis was performed to compute the ultimate shear strength of hybrid girder. Imperfection analysis was performed by varying the magnitude of imperfection on web panel of hybrid plate girder to compare the variation in ultimate shear strength. The study was also done by varying the yield strength and slenderness ratio of web panel. The result of the study indicates that the ultimate shear strength of hybrid plate girder decreases with increase in the magnitude of initial imperfection. The effect of imperfection on shear strength was significantly high for plate girder with low web slenderness ratio and high yield strength of web panel. The maximum lateral as well as the vertical deflection at ultimate strength state of the model increases with increase in magnitude of imperfection.
