Stability of Steel Decks in Cable Stayed Bridges Having Delta Framing Towers

Abstract

Steel decks in cable stayed Bridges with Delta Framing Towers are considered one of the most important types incable stayed bridge category (truss girders or box steel girders). In order to evaluate the potential of decreasinghorizontal drift in super-structure. Four suggested bracing systems were investigated in this paper geometry of „TataraBridge‟ deck and its steel towers will be used. The “Tatara Bridge” is one of the world‟s longest steel-concrete hybridcable stayed bridge. The side spans consist of steel and pre-stressed concrete precast concrete (PC) girders about 50mfrom anchored spans.
