Seismic Design for concrete silos in Canada.
Seismic Design for concrete silos in Canada.
(OP)
I am currently looking at NBC 2010 Earthquake Load and Effects to design foundations for a concrete silo. I have read the Users Guide - 2010 Structural Commentaries (Part 4 of Division B) and it states that NBC subsection 4.1.8 apply only to the seismic design of new buildings and should not be used for special structures. So concrete silos are not applied to this?? Where do I go for special structure design for seismic effects. International Building Code?? Anyone have thoughts on this? I am working out of the states and would like to know where to find any information.

It is a large 10 pack with interstice bins. 28 bins total. ASCE 7-10 has a section for non-building structures and references silos. This method seems valid but is not using the Canadian code. I compared the values I obtained using this method versus the Canadian building code method and the values are very close for seismic base shear forces, even though the NBC commentary states that it is not used for special structures. I am not familiar with the AHJ. I will have to look into it.
