Evaluation of reinforcement detailing with respect to the amount and spacing of transverse rein- forcement, 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 analy- sis and ductility estimation is presented as representative of the approach used to evaluate all other selected bridges.
