    ASTM A761 / A761M

    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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.
