Considering the disastrous consequences of the oil tank failure,it is of great importance to ensure the safety of the large-scale oil tank under earthquakes.This study sheds light on investigating the dynamic response of a prototype 100,000 m 3 cylindrical oil-storage tank under various seismic excitations.The foundation of the tank is also considered in this study so that the obtained US5772361A - Extendable anchor base septic tank - Google Vertical line 29 can be anywhere in the tank,but preferably is near or at the center of the tank.Each anchor plate when at maximum horizontal extension from the tank,extends preferably as far 42 as the outer edge 38 of the top 26 of the tank.The anchor plate is preferably integrally molded with the tank,that is,molded with the tank as a unit.Title Dogra Chair Professor at IndianLocation India500+ connectionsSeismic Analysis of Open-Top Storage Tanks With Flexible May 08,2019 partially anchored liquid storage tanks maximum slenderness ratios#0183;Three different tank geometries with liquid height to tank radius aspect ratios of 0.67,1.0,and 3.0 were selected representing broad,nominal,and slender tanks.These tanks were subjected to two different hydrodynamic loading based on Housner's and JacobsenVeletsos' pressure distributions,which forms the basis of design provisions used

The moment magnifier method is an approximation method allowed in ACI31810.10 for concrete walls with a slenderness ratio less than or equal to 100.If the slenderness ratio is less than 34,then the moment magnifier is equal to 1 and requires no additional analysis.The design procedure and equations below follow ACI-31810.12.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextUS5772361A - Extendable anchor base septic tank - Google Vertical line 29 can be anywhere in the tank,but preferably is near or at the center of the tank.Each anchor plate when at maximum horizontal extension from the tank,extends preferably as far 42 as the outer edge 38 of the top 26 of the tank.The anchor plate is preferably integrally molded with the tank,that is,molded with the tank as a unit.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextDynamic Behaviour and Seismic Response of GroundMay 12,2018 partially anchored liquid storage tanks maximum slenderness ratios#0183;Liquid storage tank such as in water distribution systems,petroleum plants etc.,constitute a vital component of life line systems.Reducing earthquake effects on liquid storage tanks,to minimize the environmental and economic impact of these effects,have always been an important engineering concern.In this paper,the dynamic behavior of cylindrical ground supported concrete water tanks
