Verification of ODOT's Load Rating Analysis Programs for Metal Pipe and Arch Culverts

TL;DRAbstract

The main objective of this study was to evaluate and improve the Ohio Department of Transportation's (ODOT's) current load rating procedures for corrugated metal culverts. This objective is achieved by testing 39 in-service culverts under static and dynamic loads, by evaluating the response of test culverts using available theoretical methods and numerical simulations, and by evaluating and advancing the current analysis tools and load rating methods based on the analytical and experimental evidence generated in this research. The experimental program was conducted to investigate the influence of several parameters on the field performance of culverts in Ohio. These parameters include backfill height, various static and dynamic load applications, and existing condition, size, shape, and other properties of corrugated metal culverts. Experimental results show that culvert deflections decrease nonlinearly with increasing backfill height. Deflections and strains were nearly zero in deep c
