End zone cracking of pretensioned concrete girders has been become more prevalent due to the increased use of high-strength concrete, deep girders, thin webs, and high prestress forces. This paper provides a methodology for analytically simulating the behavior of pretensioned concrete members. The finite element method approach developed in this study was used to investigate the behavior of the end zone reinforcement of the 210 ft (64 m) long, 100 in. (2500 mm) deep super girders used in construction of the Alaskan Way Viaduct replacement in Seattle, Wash. End zone reinforcement of eight girders was instrumented for this purpose. The finite element analysis accurately predicted the measurements collected from the instrumented girders. The results of the finite element are compared with those of several other methods.
