For an existing 110' high elevated water tank located in seismic zone 4 would you recommend a static analysis per 97' UBC standards or a full blown site specific dynamic analysis. Analysis is being performed for a retrofit consideration. Per 97' UBC if the structures period is less than 0.7 sec then per code you are allowed to perform a static analysis, above 0.7 sec code recommends dynamic. We have heard from a few source that a dynamic analysis should definitely be performed on a inverted pendulum type structure like this. Please advise on your theories on how to accurately model this type of structure.
