Abstract
A composite concrete reinforced corrugated metal arch-type structure comprises a first set of shaped corrugated metal plates interconnected in a manner to define a base arch structure with the corrugations extending transversely of the longitudinal length of the arch and a second series of shaped corrugated metal plates 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 corrugations of the second series of plates secured to the crests of the first set of plates. The interconnected series of second plates and the first set of plates define individual, transversely extending, enclosed continuous cavities filled with concrete to define an interface of the concrete enclosed by the metal interior surfaces of the second series of crests and first set of troughs. The interior surfaces of the cavities for each of the first and second plates have means for providing a shear bond at the concrete-metal interface to provide individual curved beams transversing the arch whereby the structure provides positive and negative bending resistance and combined bending and axial load resistance to superimposed loads.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
