Abstract

An extradosed bridge is characterized by very less values of the ratio of pylon height to main span of cablestayed bridges. The obvious advantages of extradosed bridges with span length less than 250 m compel to studyvarious parameters in detail. In the present paper, an attempt has been made to study the effects of havingdifferent types of connections between pylon and deck girders. Effects of structural response such as pylonmoment, girder moment, etc., have been studied in detail. The influence of seismic zone, static and geometricalnonlinearity has been studied on the effects of deck-pylon connections. Responses due to various live loadpatterns on extradosed bridges have been demonstrated.Keywords: Extradosed bridges, geometric nonlinearity, seismic effects, stiffness-based FEM analysis
