As per my knowledge Indian guidlines says that the height of petroleum product storage tank shall not be more than 20 m.What is a reason for the same ? I have seen in gulf the petroleum product storage height is more than 20 m.

Is this an underground tank?Where is 'P' coming from?Information not clear. Is this uplift caused by seismic load? which will be possible for this high magnitude at high seismic zone. Is this upliftVivek19 Is that net uplift some sort of an empty tank buoyance force with some factor of safety,to keep the empty tank from floating away?post vendor drawings of tank if you can.you may have units wrong.idk.i have designed a few tank foundation and never had problems with uplift.oA flat bottom pressurized tank can generate large uplift forces. Check your units and equations to make sure you have it figured right,though. AJStephen (Mechanical),Actually that is an API 620 Tank only.But as per some clause from API 620 ,they need to calculate the Uplift as per API 6Agree with delagina. The pressure in pressurized tank will not cause any uplift on foundation.It only cause tension on tank structure itself.unless your pressurized tank is filled with hydrogen or similar light air,then it will cause uplift.Related searches for API 620 tanks slab foundations

Foundations of aboveground steel tanks

The proposed construction is similar to the API Std.650,but the foundation ring is moved in the outside direction where it can not be influenced of the load of the shell and the tank roof upon it.When there is soil settlement under the tank,the reinforced concrete ring does not allow full drain of the water so that this solution is unfortunate.Foundation and Civil Services Advance Tank ConstructionAdvance Tank and Constructions Foundation and Civil Group specializes in the engineering and installation of tank foundations and secondary containment solutions.Our experienced teams have performed concrete foundation and containment work at a variety of industrial sites,including refineries and chemical plants.Draft - For Committee Use Only TANK -Aug 22,2008 API 620 tanks slab foundations#0183;A heating system provided in the base slab or soil below the tank to prevent freezing of the soil and prevent frost heave.3.2.2.3 Base Slab The base slab is a continuous concrete base supporting the tank system.This base may be either at grade or elevated and may be either supported by soil or piles.3.2.2.4 Dike Wall
