Model analysis of box culverts subjected to highway loading

Abstract

The strain distribution and the deflections of reinforced-concrete box culverts associated with highway loading are determined by testing scale models. Two types of scale models were constructured: 1/6-size concrete models and a 1/24-size photoelastic model. The concrete models were instrumented with electric-resistance strain gages, and the deflections were measured with dial indicators. Strain and deflection data due to live loading are compared with values from testing of prototypes. The results of testing indicate that box-culvert sections conforming to ASTM C 850 are overdesigned structurally. Testing of models of a redesigned box culvert indicates that they perform satisfactorily.
