This specification covers corrugated steel structural plate, zinc-coated, used in the construction of pipe, pipe-arches, arches, underpasses, and special shapes for field assembly. Appropriate fasteners and accessory materials are also described. The pipe, arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels. The base steel shall be made by any of the following processes: open-hearth, basic oxygen, or electric furnace. The base metal analysis shall conform to the required chemical composition for sulfur, carbon, manganese, phosphorus, and silicon. The mechanical properties of the flat plate material prior to corrugating shall conform to the required value for yield strength, tensile strength and elongation. When specified, metal bearings for arches shall be cold-formed channels made from flat plate material while steel members for circumferential or longitudinal stiff reeners, or secondary structural components, shall be fabricated from rolled shapes or from flat plate material. Structural plates shall be fabricated from flat sheets or plates, punched for bolted lap seams and curved to the required radius. Corrugations shall form smooth continuous curves and tangents. The bolt holes shall be punched so that all plates having like dimensions, curvature, and same size and number of bolts per foot of seam shall be interchangeable. All structural plates, including fittings and cut ends, shall be zinc coated after cutting, corrugating, punching of holes, and welding.1.1 This specification covers corrugated steel structural plate, zinc-coated, used in the construction of pipe, pipe-arches, arches, underpasses, and special shapes for field assembly. Appropriate fasteners and accessory materials are also described. The pipe, arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels.1.2 This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and plate thickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection of plate thickness, type of bedding and backfill, manufacture in the plant, and care in the installation. The purchaser must correlate the preceding factors and also the corrosion and abrasion requirements of the field installation with the plate thickness. The structural design of corrugated steel structural plate pipe and the proper installation procedures are described in Practices A796/A796M and A807/A807M.1.3 This specification is applicable to orders in either inch-pound units (as A761) or SI units (as A761M). Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text, but they are the applicable values when the material is ordered to A761M.1.4 This specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers corrugated steel pipe and pipe-arches, ribbed and composite ribbed steel pipe, ribbed pipe with metallic-coated inserts, closed rib steel pipe, composite corrugated steel pipe, and steel structural plate pipe, pipe-arches, and underpasses for use as storm sewers and sanitary sewers, and other buried applications. The design load or pressure on a pipe is comprised of earth load, live load, and impact load. These loads are applied as fluid pressure acting on the pipe periphery. Strength requirements for wall strength, buckling strength, and seam strength may be determined by either the allowable stress design method or by the load and resistance design method. The thrust in the pipe wall shall be checked by three criteria. Each considers the joint function of the steel pipe and the surrounding soil envelope. The pipe design using the LRFD method is presented. The pipe shall have enough rigidity to withstand the forces that are normally applied during shipment, handling, and installation. Where pipe is to be placed under roads, streets, or freeways, the minimum cover requirements shall be determined. Corrugated steel pipe composed of a smooth interior steel liner and a corrugated steel exterior shell that are attached integrally at the continuous helical lock seam shall be designed as specified. Smooth pipe with ribs shall be designed on the same basis as a standard corrugated steel pipe. Composite corrugated steel pipe of all types shall be designed on the same basis as standard corrugated steel pipe with a curve and tangent profile. Pipe-arch and underpass design shall be similar to round pipe using twice the top radius as the span. The performance of a flexible corrugated steel pipe is dependent on soil-structure interaction and soil stiffness. The construction and installation of corrugated steel pipe and pipe-arches and steel structural plate pipe, pipe-arches, arches, and underpasses shall conform accordingly.1.1 This practice covers the structural design of corrugated steel pipe and pipe-arches, ribbed and composite ribbed steel pipe, ribbed pipe with metallic-coated inserts, closed rib steel pipe, composite corrugated steel pipe, and steel structural plate pipe, pipe-arches, and underpasses for use as storm sewers and sanitary sewers, and other buried applications. Ribbed and composite ribbed steel pipe, ribbed pipe with metallic-coated inserts, closed rib steel pipe, and composite corrugated steel pipe shall be of helical fabrication having a continuous lockseam. This practice is for pipe installed in a trench or embankment and subjected to earth loads and live loads. It must be recognized that a buried corrugated steel pipe is a composite structure made up of the steel ring and the soil envelope, and both elements play a vital part in the structural design of this type of structure. This practice applies to structures installed in accordance with Practices A798/A798M or A807/A807M.1.2 Corrugated steel pipe and pipe-arches shall be of annular fabrication using riveted or spot-welded seams, or of helical fabrication having a continuous lockseam or welded seam.1.3 Structural plate pipe, pipe-arches, underpasses, and arches are fabricated in separate plates that, when assembled at the job site by bolting, form the required shape.1.4 Deep corrugated plates are covered in this standard as a means of providing design properties only. The structural design of deep corrugated structures is not supported by this standard.1.5 Units—This specification is applicable to design in inch-pound units as A796 or in SI units as A796M. Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text for clarity, but they are the applicable values when the design is done per A796M.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The structural design of corrugated aluminum structural plate pipe and the proper installation procedures are given in Practices B790/B790M and B789/B789M, respectively. A procedure for using life-cycle cost analysis techniques to evaluate alternate drainage system designs using corrugated metal pipe is given in Practice A930.1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
