In addition to embedded depth,the minimum diameter required for anchor bolts is 1/2 inch (12.7 mm) per the International Building Code (IBC).As with maximum spacing,this is a minimum requirement.Increasing the diameter to 5/8 inches is usually a good way to allow for some margin of error,particularly in seismic regions.Useful Calculation sheets (excel and mathcad files) for D Tank inside diameter H2 Height of tank shell H Maximum design liquid level Ht Test Liquid Level 1 .4 MATERIAL MECHANICAL PROPERTIES Component Material Tensile Yield Corrosion Stress Stress Allowance S( / 60m diameter mechanically anchored steel tanks#178;)St(N/mm 60m diameter mechanically anchored steel tanks#178;)()S( / 60m diameter mechanically anchored steel tanks#178;)Sy(N/mm 60m diameter mechanically anchored steel tanks#178;)y( ) c.a.(mm)() DESIGN OF STEEL STORAGE TANKS AS PER API-650 SELF-SUPPORTED CONE ROOF DESIGN DATAUplift for Anchored Steel Tanks - Foundation engineering May 17,2005 60m diameter mechanically anchored steel tanks#0183;I am looking at a reference for calculating maximum uplift loads for anchorage (at the outter diameter) for steel tanks.The max uplift for both Wind and Seismic loads are calculated as (4*M/D)-W,where M is moment due to seismic or wind load,D is dia.of tank and W is dead load of steel shell minus corrosion allowance.Why is there a factor of 4 for the moment?
Tanks in API 650 Welded Steel Tanks for Oil Storage (API,2007) is most applied.Theoretically,it considers two response modes of a tank and its contents impulsive and convective (Housner,1963).This procedure applies to anchored steel tanks,which are the most commonly used variety,and is of high seismic concern in Taiwan.It is also Tanks L/d Ratio - Industrial Professionals - Cheresources Tanks L/d Ratio - posted in Industrial Professionals Dear Sir,What is the preferred L/D ratio for atmospheric tanks.Say for atmospheric water storage tanks- Length greater than Diameter (or) Diameter greater than Length is preferred? Does L/D ratio also varies with increase in tank capacities?
