11.3.5 Evaluation of tank settlement according to API standard 653. Measurement of tank settlement comprises three components: uniform settlement, planar tilt, and out-of-plane settlement. While excessive uniform settlement and uniform settlement may not impair the structural integrity of tanks, they can cause serviceability issues.Tank design - wordFeb 04, 2016 · Wind blowing over the top of the tank can also cause a negative pressure or vacuum to act on the tank roof. 4.5.2.3.7.1.1 Overturning Stability against Wind Load Figure 4-14 Overturning Stability against Wind Load The wind pressure used in the analysis is given by API 650: = 0.86 kPa (V/190)² Wind pressure on the vertical projected areas of api standard 650 tank overturning stabilityAGENDA ITEM: 650-472 Load CombinationsThe safety factor used in API 650 3.11 for overturning of an empty tank subject to wind is 1.5. For tanks with liquid levels between empty and full, a sliding scale safety factor is proposed. For example, the safety factor required for a half-full tank would be the average of the safety factors for empty and full tanks, or (1.5 + 2.5)/2 = 2.0.

API 650 is a standard, and does not carry the weight of law in most if not all jurisdictions. That being said, the committee has spent much time on the subject of overturning and anchorage of late, and the approach given in the standard is considered to be both conservative and economical.
