摘要： A composite concrete reinforced corrugated metal arch-type structure comprises: i) a first set of shaped corrugated metal plates (78) interconnected in a manner to define a base arch structure with the corrugations extending transversely of the longitudinal length of the arch; ii) a second series of shaped corrugated metal plates (24) interconnected in a manner to overlay the first set of interconnected plates of the base arch, the second series of plates having at least one corrugation extending transversely of the longitudinal length of the arch with the troughs of the corrugation of the second series of plates secured to the crests of the first set of plates; iii) the interconnected series of second plates and the first set of plates define individual, transversely extending, enclosed continuous cavity (80) filled with concrete (86) to define an interface of the concrete enclosed by the metal interior surfaces of the second series of crests and first set of troughs; iv) the interior surfaces of the cavity for each of the first and second plates having means (96) for providing a shear bond at the concrete-metal interface to provide individual curved beams traversing the arch whereby the structure provides positive and negative bending resistance and combined bending and axial load resistance to superimposed loads.

摘要： A reinforced metal box culvert (78) is provided which has the standard crown (82), opposing sides (80) and opposite curved haunches (84). The culvert (78) is characterized in having continuous corrugated metal sheet reinforcement (86) secured to at least the crown (82) of the culvert and extends the length of the culvert which is effective in supporting the load. The corrugated reinforcement (86) has a profile which abuts the crown corrugations with the troughs of the reinforcement (86) being secured to the crests of the corrugated crown (82). The corrugated reinforcement (86) sheet has a curvature complementary to the corrugated crown (82) to facilitate securement. The continuous reinforcement (86), as secured to the culvert in an uninterrupted manner, provides an optimum load carrying capacity for selected extent of reinforcement provided by the reinforcement metal sheets (86).
