THE EFFECT OF MULTI-ANGLE, SPATIALLY VARIABLE SEISMIC MOTIONS ON CABLE-STAYED BRIDGES
Abstract eng: The spatial variability of the ground motion can be a key factor to the design of cable-stayed bridges to resist seismic actions due to the critical effect of the asynchronous movement that it introduces between the towers. Cable-stayed bridges are landmark structures consisting key parts of transportation networks and their integrity must be ensured even under extreme seismic events. This work examines the effect that spatially variable ground motions have on the towers of a cable-stayed bridge with 200 m main span. Two different orientations of the structure are examined in an attempt to shed light into the orientation-dependent seismic response of the towers. Additionally, three different propagation velocities of the seismic waves are adopted and the results are compared to those obtained under synchronous ground motions.
