Earthquake Design Considerations for Anchorages in Industrial Facilities
Anchorages of tanks, vessels and other significant structures in petrochemical facilities are subject to code requirements and must be engineered so that their design strength equals or exceeds the factored loads from load combinations that include earthquake (seismic) load effects. Depending on the Seismic Design Category, there are additional requirements in codes and standards that either require a ductile failure mode for the anchorage or require elastic behavior of the anchorage when it is subjected to the displacement demands of the design seismic event. There are additional seismic design considerations that are recommended for anchorages within petrochemical facilities in order to provide adequate performance when subjected to seismic loads, and are dependant upon the type of nonbuilding (petrochemical) structure under consideration. The state-of-the-practice report Design of Anchorages in Petrochemical Facilities soon to be issued by the ASCE Task Committee on Anchorage (Petrochemical Committee) provides guidelines that should help practicing engineers design anchorages in industrial facilities for earthquake loads. Topics related to petrochemical facility anchorage seismic design that are addressed in this guideline include references to and highlights from building codes and industry standards for determining seismic design loads; recommendations for implementing ductility requirements; and special detailing considerations for anchorage of typical nonbuilding structures within petrochemical facilities.
