Differences in designing high-speed railway bridges and highway bridges

ABSTRACT: Live Loads of High Speed Railways Bridges are quite larger than those used for the design of Highway Bridges, resulting in important differences between the design criteria used in each case. The aim of this paper is to show to experimented designers of highway bridges the differences between the design criteria of both kinds of bridges, particularly from the functional, morphological and structural point of view. Decks, piers, abutments, and structural bearings will be considered.
