Architectural Institute of Japan - Design Recommendation For Storage Tanks and Their Supports with Emphasis On Seismic Design, 2010 Edition
Foreword
The Architectural Institute of Japan set up a “Sub-Committee for Design of Storage Tanks” to provide a recommendation of the seismic design for the various types of storage tanks in common use throughout Japan. The Sub-Committee first published “Design Recommendation for Storage Tanks and Their Supports” in 1984, and amended it in the 1990, 1996 and 2010 publications. This current revised recommendation provides bulk material pressures for silos and further guidance on seismic design methods for storage tanks based on the horizontal loadcarrying
capacity in the structure.
It is envisaged by publishing the English version of “Design Recommendation for Storage Tanks and Their Supports” that the above unique design recommendation will be promoted to the overseas countries who are concerned on the design of storage tanks and the activities of the Architectural Institute of Japan will be introduced them too. It is addressed how this recommendation is in an advanced standard in terms of the theory of the restoring force characteristics of the structure considering the Elephant Foot Bulge (EFB), the effect of the uplifting tank and the plastic deformation of the bottom plate at the shell-to-bottom juncture in the event of earthquake, the design spectrum for sloshing in tanks, the design pressure for silos, and the design methods for the under-ground storage tanks as well. The body of the recommendation was completely translated into English but the translation of the commentary was limited to the minimum necessary parts for understanding and utilising the theories and equations in the body. The sections 2.7 Timbers and 4.9 Wooden Storage Tanks are omitted as they are not common in overseas countries. Listing of some Japanese references are omitted and some new references are added in this English version.
It is worthy of note that the contents of this recommendation have been verified and their efficacy confirmed by reference to data obtained from the tanks and silos damaged during recent earthquakes in Japan, including the Hanshin-Awaji Great Earthquake in 1995 and the Niigataken Chuetu-oki Earthquake in 2007.
