Download or read book Shear Strength and Shear Fatigue Behavior of Full-scale Prestressed Concrete Box Girders written by Anita K. Buzick and published by . This book was released on 1999 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two full-scale prestressed concrete box girders with identical properties were tested. The loads were placed so that shear rather than flexure would govern failure. The first girder was tested to evaluate ultimate shear strength under monotonic loading. The second girder was subjected to one-half million cycles of repeated loading and nine static overloads before its ultimate strength test. The results indicated that the effect of repeated loading on the shear strength of a shear dominated girder is less significant than that of a flexure dominated girder.
