Abstract: Staged construction is the practice in which traffic is maintained on a bridge while it is constructed in phases. When cast-in-place concrete decks are used with staged construction, the concrete deck must cure while ...

Abstract: A monitoring strategy for investigating the long-term longitudinal deflections at the expansion joints of the I-35W St. Anthony Falls Bridge was developed as a means of inferring the integrity of the bearings. During the ...

Abstract: This paper presents a technique for computing the time-dependent behavior of reinforced and prestressed concrete as a composite material. This technique, when implemented in a finite-element model and assuming that the ...

Abstract: Typically, measurement and analysis of concrete time-dependent behaviors such as creep and shrinkage are performed under the assumption of constant temperature conditions. However, many structures in the field are subject ...

Abstract: Thermal gradients were measured through the section of the I-35W St. Anthony Falls Bridge, a posttensioned concrete box girder bridge in Minneapolis, Minnesota, over the course of 3 years. The magnitudes and shapes of the ...

Abstract: The I-35W St. Anthony Falls Bridge was constructed to replace the steel truss bridge that collapsed on August 1, 2007. The design of the replacement bridge featured a smart-bridge system. The smart-bridge concept included ...

Abstract: Staged bridge deck construction is the practice whereby a portion of a bridge is left open to traffic while the closed portion is constructed, repaired, replaced, or widened. Traffic-induced deflections and vibrations ...

Abstract: Changes in vehicular loading over time have caused some concrete slab span bridges to rate poorly when considering modern truck weights, which leads to load posting and restrictions that in turn lengthen trucking routes. ...
