Tank Anchorage,Overstrength Factor,and Overturning

If you are in SDC A or B,the detailing requirement doesn't apply.So in those cases you can just design the anchors for the loads,or in some situations you can design the tank to be self-anchored.Section 15.7.5 kicks you to the applicable reference document to determine whether or not your specific tank or vessel qualifies to be self-anchored.Self-Anchored vs.Mechanically-Anchored Storage Tanks Mar 24,2009 self anchored tanks subject to seismic load#0183;That is correct - a self anchored storage tank has NO anchor bolts; nothing happens to it during seismic/winds loads because it has been determined that the overturning moments do not exceed the dead load resisting moment of the empty tank (the wind/seismic loads are low due to location and tank size/parameters).Seismic Performance Evaluation of Liquid Storage Tanks A simplified approach is presented for the seismic performance assessment of liquid storage tanks.The proposed methodology relies on a nonlinear static analysis,in conjunction with suitable strength ratio-ductility-period relationships,to derive the associated structural demand for the desired range of seismic
