Bridge structure

Abstract

The subject invention is an improved bridge structure comprising the use of both arch structural support systems along with suspension systems, combined together to support a multiple bridge support structure, with such multiple support systems being focused and combined through a unitary member in a center portion of the bridge, with the unitary member being an under support member in one embodiment, with such under support member supporting a portion of the bridge deck. More particularly, the subject invention is focused on utilizing multiple structural support systems for a bridge, with such multiple support systems being centered on a longitudinally extending secondary under support member, which is supported and held partially by the supplementary bridge support system, such secondary support member structurally having multiple and varied support systems and being adapted to provide an under support system as a supplementary support mechanism for the bridge structure. In summary, the subject invention comprises a secondary support system for a bridge to provide additional support to the primary support system for the bridge, such secondary support system having its forces focused on an undersupport system that is positioned beneath the bridge deck as an undersupport member that helps hold the bridge deck, along with the support provided by the primary support system.

Description

DISCUSSION OF PRIOR ART AND BACKGROUND OF INVENTION [0001] The subject invention relates to bridge structures and is conceived as an improved structural arrangement that combines multiple types of support systems to increase the bridge strength and stability of the bridge. [0002] The purpose of increasing a bridge strength is manifest when consideration is given to the fact that most highway bridges are now subjected to heavier loads, all with increasing frequency. This load factor is caused in large party by heavy truck traffic, along with the increased passenger vehicle traffic. These load factors yield considerable stress on a bridge's strength and stability. Railroad bridges are generally subjected to the same type of structural stress. [0003] Moreover, in certain geographic areas, highways and railroad bridges are subjected to severe winds that appear to be increasing in intensity by reason of developing unusual weather patterns. These and other factors, including earth tremors...
