Why was there a difference in API 650 Annex E?Why was there a difference in API 650 Annex E?The small disparity in results could be due to the fact that the approach in Annex E of API 650 is for tanks of rigid walls and a rigid foundation, whereas the New Zealand and Japanese documents consider tank and foundation flexibility.Review of API 650 Annex E Design of large steel welded API 650 unanchored flat-bottom tank structural shapes What are the limit states in API 650?What are the limit states in API 650?Several limit states such as hydrodynamic hoop stress, uplift, base plate stress, buckling, freeboard, and two stability mechanisms, shear and overturning are investigated. The design provisions for each of the documents were compared for identical tank geometries and seismic parameters for several different tank aspect ratios.Review of API 650 Annex E Design of large steel welded API 650 unanchored flat-bottom tank structural shapes The uplift effect of bottom plate of aboveground storage API 650 unanchored flat-bottom tank structural shapes

Thus, overturning moments satisfy all the uplift criteria in API 650 design standard for unanchored tanks . The available friction resistances at the bottom of the tanks are much larger than the disturbing wind load acting horizontally on the shell of the tanks , as shown in Table 5.

Tank Foundations Geotechnical Engineering Structural Load

b. To [email protected] tank stability, the foundation weight should be added to the tank s shell weight, Wt (see API 650 , Appendix E), and the tank should be analyzed as unanchored . c. Unless determined otherwise, the tank should be assumed to be flexible and the foundation should be designed for the full uplift forces. d. Storage Tank Foundation Design & Construction In practice the tank bottom subsidence may amount to 2 m, that is why raising of its central part may become the key factor of the long operation life period of the construction. If the construction site has soft or heaving soil at little depth (up to 3 m), which is characteristic of areas with deep seaal soil freezing, it is possible to API 650 unanchored flat-bottom tank structural shapes Seismic design rules for flat bottom cylindrical liquid API 650 unanchored flat-bottom tank structural shapesInt.
