I am designing a 125 foot diameter steel flat bottom water tank. The geotech report included a probabilistic seismic risk evaluation which they gave as a tripartite response spectra.
My question is, when comparing the acceleration from the geotech to the acceleration computed from the UBC, are both accelerations apples and apples or is one based on working stress and one based on strength design? (i.e. the 1.4 factor comes into play).
Any help is greatly appreciated.
