Abstract:
An improved continuous stay-in-place (CSIP) precast prestressed concrete panel system is developed to cover the entire width of a bridge, eliminating some of the drawbacks of the conventional stay-in-place (SIP) precast panels. This system eliminates the necessity of forming for the overhangs resulting in reduction of the time and labor required installing a large number of pieces. The precast panel has a full-length gap at the girder lines to maximize the space available to accommodate the shear connectors of the supporting girders. Shear keys and reinforced pockets are used in the transverse direction to provide continuity between the precast panels. All materials used in producing the precast panel are nonproprietary and readily available which makes this system cost comparable to that of the conventional SIP precast system. This paper describes the system.
