Designation:A796/A796M17Standard Practice forStructural Design of Corrugated Steel Pipe,Pipe-Arches,and Arches for Storm and Sanitary Sewers and OtherBuried Applications1This standard is issued under the fixed designation A796/A796M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers the structural design of corrugatedsteel pipe and pipe-arches,ribbed and composite ribbed steelpipe,ribbed pipe with metallic-coated inserts,closed rib steelpipe,composite corrugated steel pipe,and steel structural platepipe,pipe-arches,and underpasses for use as storm sewers andsanitary sewers,and other buried applications.Ribbed andcomposite ribbed steel pipe,ribbed pipe with metallic-coatedinserts,closed rib steel pipe,and composite corrugated steelpipe shall be of helical fabrication having a continuouslockseam.This practice is for pipe installed in a trench orembankment and subjected to earth loads and live loads.Itmust be recognized that a buried corrugated steel pipe is acomposite structure made up of the steel ring and the soilenvelope,and both elements play a vital part in the structuraldesign of this type of structure.This practice applies tostructures installed in accordance with Practice A798/A798Mor A807/A807M.1.2 Corrugated steel pipe and pipe-arches shall be of annu-lar fabrication using riveted or spot-welded seams,or of helicalfabrication having a continuous lockseam or welded seam.1.3 Structural plate pipe,pipe-arches,underpasses,andarches are fabricated in separate plates that,when assembled atthe job site by bolting,form the required shape.1.4 Deep corrugated plates are covered in this standard as ameans of providing design properties only.The structuraldesign of deep corrugated structures is not supported by thisstandard.1.5 This specification is applicable to design in inch-poundunits as A796 or in SI units as A796M.Inch-pound units andSI units are not necessarily equivalent.SI units are shown inbrackets in the text for clarity,but they are the applicablevalues when the design is done per A796M.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A760/A760M Specification for Corrugated Steel Pipe,Metallic-Coated for Sewers and DrainsA761/A761M Specification for Corrugated Steel StructuralPlate,Zinc-Coated,for Field-Bolted Pipe,Pipe-Arches,and ArchesA762/A762M Specification for Corrugated Steel Pipe,Poly-mer Precoated for Sewers and DrainsA798/A798M Practice for Installing Factory-Made Corru-gated Steel Pipe for Sewers and Other ApplicationsA807/A807M Practice for Installing Corrugated Steel Struc-tural Plate Pipe for Sewers and Other ApplicationsA902 Terminology Relating to Metallic Coated Steel Prod-uctsA964/A964M Specification for Corrugated Steel Box Cul-vertsA978/A978M Specification for Composite Ribbed SteelPipe,Precoated and Polyethylene Lined for Gravity FlowSanitary Sewers,Storm Sewers,and Other Special Appli-cationsA1019/A1019M Specification for Closed Rib Steel Pipewith Diameter of 36 in.900 mm or Less,PolymerPrecoated for Sewers and Drains(Withdrawn 2012)3A1042/A1042M Specification for Composite CorrugatedSteel Pipe for Sewers and Drains(Withdrawn 2015)3D698 Test Methods for Laboratory Compaction Character-istics of Soil Using Standard Effort(12,400 ft-lbf/ft3(600kN-m/m3)1This practice is under the jurisdiction of ASTM Committee A05 on Metallic-Coated Iron and Steel Products and is the direct responsibility of SubcommitteeA05.17 on Corrugated Steel Pipe Specifications.Current edition approved Feb.1,2017.Published February 2017.Originallyapproved in 1982.Last previous edition approved in 2015 as A796/A796M 15a.DOI:10.1520/A0796_A0796M-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D1556 Test Method for Density an
