The live load distribution factor (DF) equations provided by AASHTO-LRFD for the decked precast/prestressed concrete (DPPC) girder bridge system do not differentiate between a single or multilane loaded condition. This practice results in a single lane load rating penalty for DPPC girder bridges. The objective of this project is to determine DF equations which accurately predict the distribution factor of the DPPC girder bridge system when it is only subjected to single lane loading. Eight DPPC girder bridges were instrumented. Each bridge was loaded with a single load vehicle to simulate the single lane loaded condition. The experimental data was used to calibrate 3D FE models and 2D grillage models of the DPPC girder bridge system. The calibrated models were used to conduct a parametric study of the DPPC girder bridge system subjected to a single lane loaded condition. Two sets of new equations that describe the single lane loaded distribution factor for both shear and moment forces of these bridges are proposed and compared with AASHTOLRFD DF equations.

Laboratory tests were conducted to investigate the problem of shear key failure in multi-beam prestressed box girder bridges and to propose a new shear key design. Failure of shear keys will typically not only compromise the load-sharing mechanism between adjacent girders, but also may lead to the failure of the deck waterproofing system, with attendant corrosion problems. The tests consisted of monitoring relative displacements occurring across intergirder joints, produced by a simulated concentrated wheel load.

Bridge decks supported by adjacent precast/prestressed-concrete beams have become increasingly popular in recent years due to their ease of construction, shallow superstructure, and aesthetic appeal. In New York, such structures are built by placing a number of precast beams alongside one another and connecting them through grouted keyways called "shear keys". After the grout hardens, the beams are transversely post-tensioned and a composite, cast-in-place deck is poured over them. Before 1992, field inspection personnel frequently reported the appearance of longitudinal deck cracking over these partial-depth shear keys soon after construction. In response, a new system using full-depth shear keys with more transverse tendons was adopted in 1992. Since then, more than 100 such bridges have been built statewide. To evaluate their performance, a followup inspection survey was conducted in 1996 on 91 such bridges.
