Title: Time-Dependent Behavior of a Skew
Reinforced Concrete Box Girder Bridge

Publication: Concrete International
Appears on pages(s): 84-92

Abstract:Time-dependent deflections and strain histories under sustained dead load, after successively increasing overload conditions, are presented for a 1:2.82 scale reinforced concrete model of a typical two-lane prototype bridge in California having two 101.5ft (30.9-m) spans with a single column bent at the center. The model had a four-cell cross section and 45 beg skew end and center-bent diaphragms. Strain histories are also presented for the construction of the bridge model, which followed a similar sequence to that used on prototype structures in the field. Maximum dead load deflection after four months and application and removal of heavy overloads was about four times the initial deflection.
