Abstract:

Prestressed concrete box beams incorporated in a bridge project under construction in the Houston District encountered cracking in the notched (dapped) ends during fabrication. Because the members in question are trapezoidal in section and have internal voids, a similar problem could occur in any beam having a voided cross section and dapped ends. As a result, dapped end designs for the section investigated in this study, as well as for similar open-top U-beam members, were reviewed by TxDOT design engineers and by researchers from The University of Texas at Austin.
