Abstract
Cable supported bridges have been used around the world for several years due to their advantage to overcome large spans, efficiency, aesthetics and ease of construction. Several studies have been made on this kind of bridge structure, including dynamic analyses to understand the structural behavior of the bridge. Extradosed bridges, a concept of partially cable-supported bridges, started to be used since the 1990's mainly in Japan, and although their use has increased in the past several years, no major studies have been made on their dynamic behavior. The purpose of this thesis is to provide insight into how different support conditions such as integral abutments, deep foundations and soil properties influence the dynamic structural behaviour of the bridge elements such as the cables, towers and bridge deck. A time history analysis with the Northridge earthquake is performed for the longitudinal, transverse and vertical direction. A 30 finite element model and analysis was performed using SAP2000 software (Static and Dynamic Finite Elements Analysis of Structures Advanced 14.1). The results for each bridge, for different support conditions, are presented in order to understand the dynamic response of the structure.
