The analysis shall take into consideration all anticipated loading conditions and combinations, including pressure due to fluid static head, internal and external pressure, wind loads, seismic loads, roof live loads, nozzle loads, settlement, and attachment loads. The publican is intended primary to assist in the establishment of essential inspection requirements for aboveground, vertical, cylindrical, steel storage tanks, in order to minimize in-service problems and extend useful life.
Accordingly, 19 publication is intended as a general inspection, maintenance and repair guide applicable to aboveground storage tanks. However for such requirements to be properly interpreted and understood, comprehensive guidance is given on many design features, on common problems experienced during operation and on repair methods.
Widely scattered pits may be ignored.
