Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF

Description: "This research program conducted a large experimental program, which consisted of the design, construction, curing, deterioration, and structural load testing of 16 large-scale column specimens with a critical lap splice region, and then compared and calibrated models developed in the analytical program with the experimental behavior. Specimens were carefully instrumented both internally and externally to monitor the strain behavior of the concrete and reinforcing steel from specimen constructi… more

Development of precast bridge deck overhang system: technical report

Description: "The testing and analyses documented in this report (0-6100-3) provides a new equation for determining the number of shear pockets required for the various shear connector/coupler systems evaluated in this research. This equation was used to determine the number of shear pockets required for the newer TxDOT girders."

Development of a precast bridge deck overhang system

Description: This research investigated the overhang and shear capacity of a precast overhang system for potential use during the construction of bridges with precast overhang panels. The research was performed in three phases: the Phase 1 research including work specifically for the Rock Creek Bridge in Parker County, Texas; the Phase 2 research for general precast overhang panels, and; the Phase 3 research investigating the shear capacity. Grout material characteristics were also assessed for possible use… more
