The bases for the calculation of moments and shears in culverts, and in similar structures having members with portions that can be considered infinitely stiff, are given. Expressions are also given for the moments at midspan and column face sections of rectangular one-celled reinforced concrete box culverts. The basic strength characteristics in shear and flexure, the limitations of the expressions presented, and the recommended factors of safety are discussed. The applications of the above criteria to the specific design of one-celled reinforced concrete box culverts, with recommendations for allowable bond stresses and for placing and spacing of reinforcement are given. Finally, design aids are presented in three appendixes. Appendix A contains charts for midspan and column face moments in one-celled rectangular reinforced concrete box culverts having a wide range of dimensions, for two ratios of lateral to vertical load, 13 and 12 Appendix B contains interaction diagrams for yield and ultimate capacities in flexure and Appendix C contains charts for cracking load capacities of members.
