One was supported on thin-walled hollow steel (HT) piers, and the other was supported on concrete-filled tubular (CFT) piers. The CFT piers were made by filling the hollow columns of the HT piers with normal concrete.

of the T-beam bridge, in which the T-beams are transformed into hollow cells by the addition of a continuous soffit across the bottom of the structure. A cross-section of a typical three-cell box girder bridge is shown below, in comparison with a typical T-beam bridge.

In this thesis analysis and design of prestressed concrete bridges (Deck Slab, T-Girder and Box Girder) are carried out using IRC The unified concrete code (IRC) published by the Indian Road Congress usually kept as 20 for simply supported spans and 25 for continuous spans.

The Budan Bridge, shown in Fig. 1, is a reinforced continuous concrete box girder type bridge located on between Artvin and Erzurum highway, Turkey, at 55 + –56 + km.

Construction of the bridge started in and completed configuration of the bridge is a three-span, cast-in-place concrete box girder superstructure supported on reinforced concrete piers.

post tensioned simply supported prestressed concrete (PC) I-girder bridges are widely used bridge system for short to medium span (20m to 50m) highway bridges due to its moderate self weight, structural efficiency, ease of fabrication, low maintenance etc.

Prestressed concrete decks are commonly used for bridges with spans between 25m and m and provide economic, durable and aesthetic solutions in most situations where bridges are needed.

Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice. Extensively illustrated throughout, this invaluable book /5(4).

Therefore, the box girder bridges constructed in Washington prior to the s, such as the Cedar Creek Bridge, were an important precedent for future bridges" (Jones). The precast deck panel system is designed using the strip design method, where a transverse strip of the deck is analyzed as a continuous beam supported by the bridge girders.

The girders are considered rigid supports with no settlement. The strip method concept results in providing the main reinforcement in the transverse direction of the deck.

Site location is assumed to be near Socorro, New Mexico, with the bridge crossing a waterway on a normal (perpendicular) alignment. The bridge consists of ft., ft. and ft. spans, with a 50 ft.

In spliced girder bridges, precast girder segments are transported in shorter segments for handling and transportation and then spliced together to form long-span continuous bridges. It is a bridge in which the main beams comprise girders in the shape of a hollow box (rectangular or trapezoidal shape).

The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. A box girder is formed when two web plates are joined by a common flange [ ].Following the design rules specified in EC4 [], the effective width of the concrete slab is m and the cross-sectional dimensions are shown in Figure Knowing that the design concrete strength f cd is equal to f ck /γ c (f cd = 40/ = MPa), we can calculate the forces acting on the composite girder as shown in Figure The position of the plastic neutral axis can be.Bo x girder bridges are being made into use at many places.

Various studies have been performed so as to develop a more stable structure design by varying the shape of the bridge structure.
