000018395 520__ $$2eng$$a To investigate seismic damage and failure mode of a single pylon cable-stayed bridge, Puqian bridge with ‘A” shape concrete pylon is selected and a 1:20 scale model is designed, constructed and tested on shake tables at Tongji University, China. Concentrating on floating system, the performance of the bridge model was evaluated under increasing levels of seismic excitation in longitudinal direction. Testing results showed that (1) first crack appeared at the bottom section of the tower leg and extended nearly to form a cycle;(2) cracks gradually appeared above the bottom and spread up to half height of the tower at nearly equal distance;(3) final cracks appeared just above the crossing section of tower legs and concrete spalling and exposed longitudinal bars were observed. At the last several stages, the displacement at tower top abruptly increased, and the deck experienced large longitudinal and vertical vibration, and large variation of cable tension force was observed.
