Advantages of Prestressed Concrete Bridges



Owners and designers have long recognized the low initial cost, low maintenance needs and long life expectancy of prestressed concrete bridges. This is reflected in the increasing market share of prestressed concrete, which has grown from zero in 1950 to more than 55 percent today.

This growth continues very rapidly, not only for bridges in the short span range, but also for spans in excess of 150 feet which, heretofore, has been nearly the exclusive domain of structural steel.

Bridges are lifeline structures. They act, as an important page link in surface transportation network and failure of bridges during a seismic event will seriously hamper the relief and rehabilitation work. There are many cases of damage of bridges in the past earthquakes all over the world. Due to their structural simplicity, bridges are particularly vulnerable to damage and even collapse when subjected to earthquakes. The fundamental period of vibration of a majority of bridges is in the range of 0.2 to 1.2 second. In this range, the structur ....etc

Philosophers, thinkers, intellectuals all appeal, please build bridges and not walls between different communities, nationalities, countries, languages etc, to achieve universal brotherhood. This can be achieved by constructing stress ribbon bridges.
Stress ribbon bridges are very economical, aesthetical and almost maintenance free structure. They require minimal quantity of materials. They are erected independently from the existing terrain and therefore they have minimum impact upon the environment during construction.

SUITABILITY OF BRIDGE MADE WITH PRECAST COMPONENTS IN AREAS OF HIGH OR MODERATE SEISMISITY
Presented By:
Bijan Khaleghi1

Abstract

The need for rapid construction arises from the inevitable increases in traffic congestion that have occurred in the past few decades, and the corresponding costs and safety manifested in many forms, including exposure of workers to traffic hazards, and most importantly, the waste of time due to delays. Prefabricated bridge components are in increasing demand for accelerated bridge construction. P ....etc
