Seismic Performance Normalization of Bridges Using a Damping-Enhanced Strengthening Methodology
Abstract eng: In this paper, a viscoelastic layer is integrated into a fiber reinforced polymer strengthening jacket for the seismic retrofit of a three-span steel-girder bridge. The distributed damping layer is represented by a series of discrete and complex springs in the finite element model of bridge columns. Damping ensures that the bridge is operational under moderate earthquakes and strengthening mainly ensures the bridge safety under strong earthquakes. Together, they meet the multiple performance objectives under earthquakes of varying intensities.
