ABSTRACT
ABSTRACT: San Diego has commissioned a landmark pedestrian bridge from its new ballpark-over several sets of train tracks, and over a busy downtown thoroughfare-to the convention center and the San Diego Bay. The bridge design is a self-anchored suspension bridge with a single inclined pylon. The main span of the bridge is 108 m and the pylon is 40 m tall. The pylon is inclined at a 60 degree angle from the horizontal and leans over the deck to support the single pair of suspension cables. 34 individual suspenders attached to the main cable support the 6 meter wide deck from the top of the railing at only one edge of the deck. The bridge is horizontally curved and a tendon is stressed at the top of the railing. The radial force generated by the tendon above the deck elevation generates a restoring moment which balances the forces in the bridge deck.
