ASTM B790/B790M-16,Standard Practice for Structural Design of Corrugated Aluminum Pipe, Pipe-Arches, and Arches for Culverts, Storm Sewers, and Other Buried Conduits.ASTM B790/B790M-16 pdf free download.
ASTM B790/B790M-16 is intended for the structural design of corrugated aluminum pipe and pipe-arches, and aluminum structural plate pipe, pipe-arches, and arches for use as culverts, storm sewers, and other buried conduits.
ASTM B790/B790M-16 is for pipe installed in a trench or embankment and subjected to highway, railroad, and aircraft loadings. It must be recognized that buried corrugated aluminum pipes are composite structures made up of the aluminum ring and the soil envelope, and both elements play a vital part in the structural design.
5. Basis of Design
5.1 The recommendations presented herein, represent gen- erally accepted design practice. The design engineer shall, however, determine that these recommendations meet particular project needs.
5.2 This practice is not applicable for long-span structures.
Such structures require additional design considerations for both the pipe and the soil envelope. The design of long-span structures is described in the AASHTO LRFD Bridge Design Specification.
5.3 Structures designed to this standard shall meet the requirements of this standard.
7. Design Method
7.1 Strength requirements for wall strength, buckling strength, and seam strength may be determined by either the allowable stress design (ASD) method presented in Section 8, or the load and resistance factor design (LRFD) method presented in Section 9. Additionally, the design considerations in other paragraphs shall be followed for either design method.
