Simplified full-depth precast concrete deck panel systems for accelerated bridge construction

Design and Construction of a Reinforcement Free Concrete Bridge Deck on Precast Bulb Tee Girders

This presentation describes the concepts involved in design and construction of a reinforcement-free bridge deck intended to provide cost effective, durable and more rapid construction for highway bridges. The new wide flanged or bulb tee precast prestressed concrete girder sections currently used in bridges allow for a shorter effective span for the bridge deck because of the wide girder flang...

Development of Self-stressing System for Bridge Application with Emphasis on Precast Panel Deck System

Optimization of Precast Prestressed Concrete Bridge Girder Systems

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

Simulation of a bridge deck construction using precast beams supported in Virtual Reality technology

In the execution of bridge decks or viaducts, several construction methods are adopted. In this Thesis the construction methods most frequently applied in bridge decks using precast beams are presented. For the considered work a 4D (3D + time) geometric model was implemented in a virtual reality environment, which simulates the construction of a deck, allowing the visualization and interaction ...

Precast, Pretensioned, Post-Tensioned Concrete for Bridge Decks

The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con­ cept of construction or reconstruction...
