Paper Abstract

An interesting and increasingly popular method of building steel and concrete composite bridges involves the use of a large steel based structure called a box- girder. These massive structures, which have dimensions on the order of 5m x 5m x 150m with wall thickness sometimes exceeding 5 cm, are assembled by welding together many shorter (e.g. 5m x 5m x 5 m) box-girder pieces near a bridge building site.
