ASABE to Revise Shallow Post Foundation Design standard.
Press Release Summary:
American Society of Agricultural and Biological Engineers (ASABE) has initiated project to update and revise ANSI/ASAE EP486.1, Shallow Post Foundation Design, in order to better address numerous considerations. In addition to in-situ determination of soil properties, prescriptive soil bearing capacity values, and modeling analogs, concerns include safety factors relating to ASD and LRFD design methodologies, ultimate lateral strength of foundations, and minimum footing sizes.

ASABE to Revise Shallow Post Foundation Design Standard
ST JOSEPH, MICHIGAN- The American Society of Agricultural and Biological Engineers (ASABE) has initiated a project to revise the shallow post foundation design standard.
ANSI/ASAE EP486.1, Shallow Post Foundation Design, contains design procedures for shallow post foundations that resist lateral and vertical forces acting on them along with definitions, material requirements, and design equations for post foundations.
The standard is being updated to better address numerous considerations. These include: in-situ determination of soil properties;, prescriptive soil bearing capacity values, which are considered (it is felt they are too conservative for certain post foundations;), modeling analogs;, safety factors as they relate to both ASD and LRFD design methodologies, ; ultimate lateral strength of foundations, ; minimum footing sizes for plain and reinforced footings (both cast-in-place and precast), ); tests for modulus of horizontal sub grade reaction;, adequacy of the uplift equation,; effects of backfill material on lateral strength and stiffness;, and use of dry concrete mixes.
ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 240 standards currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial, or other governmental requirements, and the documents are developed by consensus in accordance with procedures approved by the American National Standards Institute. For information on revision or any other ASABE standard, contact Scott Cedarquist at 269-932-7031, cedarq@asabe.org. A current listing of all ASABE standards projects can be found on the ASABE web site at http://www.asabe.org/projects.
ASABE is an international scientific and educational organization dedicated to the advancement of engineering applicable to agricultural, food, and biological systems.
