Four basic bridge types, each consisting of steel or concrete, were initially considered. Two alternatives, a steel truss bridge and a steel arch bridge, were designed in detail. A Building Information Model was generated to visualize the two alternatives. The supporting bridge structure using cast-in-place reinforced concrete for both
Design Of Reinforced Concrete Structures ii Two-Way Slabs 1 1. Inroduction When the ratio (L/S) is less than 2.0, slab is called two-way slab, as shown in the fig. below. Bending will take place in the two directions in a dish-like form. Accordingly, main reinforcement is required in the two directions.
Cracks, water seepage and other damage often occurred in the hinge joints of the fabricated hollow slab bridge and affect the transverse integrity of the bridge. In order to solve these problems, a new type prefabricated I-girder is proposed, the girder is connected crosswise through wet joints, and the distributed bars extending from the flange are firmly connected in the wet joints. The wet ...

Slab". When placing concrete, care shall be taken to reinforcing shall be subsidiary to "Reinforced Concrete stopped or cut to clear casting as shown. Additional slab When bending is not possible reinforcing bars may be Slab reinforcing bars shall be bent to clear casting by 1". iron. Galvanization of these materials will not be required.
Its thin curved stone slabs were joined with iron dovetails so that the arch could yield without collapsing.7This articulation allowed the bridge to survive the movements of abutments bearing on spongy, plastic soils, and also the effects of moving traffic loads.
In the paper the refurbishment of a reinforced concrete slab bridge is described. The bridge had been in service for over 50 years without major repair or renovation nor with any marks of distress or cracks noted. The bridge needed refurbishment due to its low bearing capacity and its location on a military transportation route.
slab road bridge located in Chennai City, Tamilnadu, India was assessed using the nonlinear analysis software package SAP2000 and the results are reported. 2.
Nov 23, 2015 · Types of Reinforced Concrete Bridge Reinforced Slab Bridges Beam and Slab Bridges For short spans, a solid reinforced concrete slab, generally cast in-situ rather than precast, is the simplest designUp to about 25m span, such voided slabs are more economical than prestressed slabs.
