bridge engineering by ponnusamy pdf

The first bridges were made by nature as simple as a log fallen across a stream. The first bridges made by humans were probably spans of wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Most of these early bridges could not support heavy weights or withstand strong currents. It was these inadequacies which led to the development of better bridges.The oldest surviving stone bridge in China is the Zhaozhou Bridge, built from 595 to 605 AD during the Sui Dynasty. T ....etc

It is more preferable, both ecological and economical to upgrade bridges rather than demolish and rebuild. The deterioration of the environmental influences and traffic loads bridges requires rehabilitation and renewal programs to maintain even current service levels on the bridge infrastructure network. There is an increased demand for high durability, long life, reduced costs of maintenance and optimization cost / performance. Advanced composite systems have now become a viable method to strengthen the existing bridges in the world. This arti ....etc

This is a very attractive design to include in your railroad. It follows a construction style similar to our Pony Truss bridge. However, it has a clear difference that gives it a character of its own and will add more interest and variety to its line.
Examples of this and its counterpart, the inverted rope bridge, can still be seen along the Penrith line, Keswick and the Cockermouth Railway. Despite being a standard branch, the track crossed the Greta River eight times using both vertical and inverted examples of rope bridges.
