Experimental Shear Behavior of Fiber Reinforced Composite Corrugated Plate Girders at Intermediate Supports

Abstract

Bridges with corrugated steel webs have been extensivelyconstructed in different countries. A trapezoidally corrugatedsteel plate is composed of a series of longitudinal andinclined subpanels. For a steel corrugated web girder, it isassumed that the web carries merely shear forces due to theaccordion effect [1,2]. The web in such a girder was found tocarry insignificant longitudinal stresses from the primaryflexure. Consequently, the bending moment is nearly carriedby its flanges. Thus, it is worth pointing out that the shearstrength can be determined without consideration ofmoment-shear interaction. But it was found that problem inan area where intermediate supports that shear forces arecompletely carried by web, and found that the value of theshear resistance, which is a concrete slab by almost beneglected. In recent years has been the study of differenttypes of materials to increase the efficiency of concrete andincrease the shear forces at the intermediate supports. Thusin this research, the effect of adding fiber to the concrete incomposite corrugated plate girders at intermediate supportswas investigated.
