Abstract:
The use of bridges dates from antiquity when man built rude bridges in imitation of nature, but bridge design as a science did not begin to emerge until the 17th Century. Bridge design has progressed with the development of materials, and today reinforced concrete and steel are the prime materials in bridge construction.
