• Experimental tests on half-scale, hollow-core and cast-in-place concrete arch culvert models were completed along with finite element and STAAD analyses for each. The main objectives were: to evaluate if a hollow-core culvert was able to sustain a 9.03-kip applied load without failure; to assess if hollow-core structure responses were comparable to cast-in-place ones; and to develop computer simulations capable of predicting hollow-core culvert responses of different configurations.Based on experimental test results, neither concrete culvert is expected to reach its elastic limit in a full-scale application since the soil cover fails in bearing prior to the traffic load reaching the arch. When the load is applied on top of the culverts, both models can sustain the 9.03 kips without undergoing failure. Regarding finite element analyses, simulations developed were unable to be calibrated with experimental data since the program did not appear to include forces acting between the top adjacent segments or the soil bearing failure above the arch.
