Title: Seismic Design Guidelines for Squat Composite- Jacketed Circular and Rectangular Reinforced Concrete Bridge Columns

Abstract:An object-oriented computer code, based on a moment-curvature analysis with inclusion of fiber-reinforced polymer-confined concrete models, was developed to predict the seismic performance of reinforced concrete squat bridge columns. The study involved seismic assessment of as-built shear-deficient columns in addition to performance prediction of ductile composite-jacketed columns. For as-built columns, the code assessed the accuracy of several shear strength models using experimental data of 65 shear-deficient columns. For composite-jacketed columns, the developed software was calibrated through a parametric study of two displacement models and six different concrete confinement models. Subsequently, a methodology for the seismic design of shear-deficient columns upgraded with composite-material jackets was devised.
