Seismic Evaluation of Reinforced Concrete Piers in Low to Moderate Seismic Regions

Evaluation of reinforcement detailing with respect to the amount and spacing of transverse reinforcement, development length, and splice length based on seismic provisions for seven Pennsylvania bridges is discussed. The selection of prototype bridges as representative of the stock of all PA bridges for the study are explained. A case study of seismic evaluation of one of the bridges selected based on finite element analysis and ductility estimation is presented as representative of the approach used to evaluate all other selected bridges.
