Web-splitting cracks have received a good deal of attention
in the literature. Previous research has focused on
the causes,1,2 design models,3–6 reject/repair criteria,7 and
control of web-splitting cracks.3,8,9 Research presented in
this paper adds to the body of knowledge by comparing
various detailing schemes for controlling or impeding websplitting
cracks. Schemes included in the research program
were vertical end-region reinforcement as required by the
2010 American Association of State Highway and Transportation
Officials’ AASHTO LRFD Bridge Design Specifications,
10 increased end-region vertical reinforcement
using 1 in. (25 mm) diameter bars, vertical end-region
posttensioning, and partial debonding of 45% of prestressing
strands.
