The Largest Reinforced Concrete Bridge in America

Design of reinforced concrete bridge frames by heuristic optimization

This paper deals with the economic optimization of reinforced concrete box frames used in road construction. It shows the efficiency of four heuristic algorithms applied to a problem of 50 design variables. Heuristic methods used are the random walk and the descent local search. The metaheuristic methods are the threshold accepting and the simulated annealing. The four methods have been applied...

Performance Evaluation of an FRP-Reinforced Concrete Bridge

As part of a larger project to investigate the use of Fiber-Reinforced Polymer (FRP) materials in bridge construction, a short-span FRP-reinforced concrete bridge was installed in central Missouri. The Walters Street Bridge is a precast concrete panel bridge reinforced with both glass FRP (GFRP) and carbon FRP (CFRP) reinforcing bars. It was designed according to the American Concrete Institute...

Reinforced Concrete Bridge Piers Subjected to Reversed Cyclic Loading

Sixteen large-scale reinforced concrete specimens without web reinforcements were tested to study the behavior of typical bridge piers subjected to deflection reversals that were large enough to cause extensive yielding of the longitudinal reinforcement. The different parameters considered included shear spanto-depth ratio, percentage of longitudinal reinforcement, frequency of the applied load...

The Economic Impact of Implementing Nondestructive Testing of Reinforced Concrete Bridge Decks in Indiana

Glass Fibre Reinforced Concrete

Glass Fibre Reinforced Concrete is recent introduction in the field of concrete technology. The present day world is witnessing the construction of very challenging and difficult Civil Engineering Structures. Concrete being the most important and widely used material is called upon to possess very high strength and sufficient workability properties. Concrete the most widely used consrtuction ma...
