the bridge deck slab. Sand-coated GFRP bars were used for the top mat of the bridge deck slab (No. 20, 19.1 mm diameter) while galvanized steel bars 15M and 20M were used for the bottom mat of the bridge deck slab. The GFRP bars were made of high strength E-glass fibers with a fiber content of 76.8% (by weight) in a vinyl ester Depending on the slab type and the span width, the level of support work can be reduced to partial - or even deleted. The major advantage of this system is the large available span widths of the prestressed floor slabs and the minimal support requirements.

loads in right slab-and-girder bridges are sometimes unsafe and often too conservative. A slab-and-girder bridge system is a favored structural choice both on economic and on aesthetic grounds. It is so named because it consists of two major structural elements. These are a reinforced-concrete slab that serves as the roadway and simplified method for the design of reinforced concrete bridge slabs was established and set forth in the AASHO specifications.

Reinforced concrete (RC) structures in a marine environment deteriorate with time due to chloride-induced corrosion of reinforcing bars. Since the RC deck slabs of jetty structures are exposed to a very aggressive environment, higher deterioration rates can develop. The plan layout of the reinforced skew bridge slab is as shown in Figures 1 to 5. In this study, the width of lane or width of carriageway is deliberately kept same to study the effect. The width of carriageway is kept 5 m for all bridge models. The input data given for the buildings is detailed below.
