Shear Behavior of Small Span Single and Double Precast Reinforced Concrete Box Culverts
This study presents two full-scale test results of shear behavior of 1.22 m x 1.22 m x 1.22 m (4 ft x 4 ft x 4 ft) precast reinforced concrete box culverts. One single and one double box jointed together without grouting were tested. A monotonically increasing load was applied through a 254 mm x 508 mm (10 in x 20 in) load plate in order to simulate the HS20 truckload per AASHTO LRFD bridge design specifications. Instrumentation included strain gauges, high-resolution laser deflection sensor, and automated data acquisition. Laser sensor data and dial gauge readings were recorded to measure the deflection profile of the box culvert. Strain gauges were placed on the steel reinforcement to measure axial strain at the locations of maximum positive and negative bending moments. The test results include reporting the loads at which each crack initiated and propagated. The displacement profile of the top slab from the laser instrumentation output is also reported.
