Abstract
This paper presents a reliability-based analysis of reinforced concrete slab culverts constructed as per the design recommendation of the Ministry of Road Transport and Highways (MORTH) at the flexural limit states. Hasofer and Lind's technique is employed to evaluate reliability index, β, which is a measure of probability of failure. The results indicate that the nominal probability of failure of slab culverts designed as per MORTH's recommendations at the limit state of collapse in flexure lies in the order of 10 -5 to 10 -8, which reveal that the designs are conservative (in comparison with AASHTO's recommendations), and the degree of conservatism is not uniform for all spans.
