Dynamic Behavior of a Damping-Enhanced Strengthening System for Seismic Retrofit of RC Columns
In this paper, a damping-enhanced strengthening technique is introduced for seismic retrofitting of reinforced concrete (RC) columns for multiple performance objectives. This technique involves an integrated and compact system of fiber reinforced polymer (FRP) sheets and viscoelastic (VE) layers. The effect of various parameters of VE layers on the dynamic response of a column was studied. Shear strain distribution of VE layers was analyzed to help understand VE material effects on the performance of the column. Numerical results indicated that the proposed technique is very effective in reducing not only the acceleration response but also the displacement response of the column.
