Ultimate Strength of Deck Arch with Continuous Stiffening Girder

Abstract

This paper is concerned with the ultimate strength of deck arch with continuous stiffening girder. Three analytical models designed same as actual bridges are considered and the ultimate load is calculated by means of the elasto-plastic and finite displacement analysis. This paper also refers to the relationship between the ultimate load and the initial yielding load through the elastic and finite displacement analysis in order to investigate the ultimate strength in the practical bridge design work.
