Liquid-containing storage tanks are important structures in industrial complexes.Because earthquake damages to liquid storage tanks can cause structural collapse,fires,and hazardous material leaks,there have been continuous efforts to mitigate earthquake damages using seismic fragility analysis.In this regard,this study focuses on the seismic responses and fragility of liquid storage tanks.Seismic Fragility Analysis of Steel Liquid Storage Tanks Liquid-containing storage tanks are important structures in industrial complexes.Because earthquake damages to liquid storage tanks can cause structural collapse,fires,and hazardous material leaks,there have been continuous efforts to mitigate earthquake damages using seismic fragility analysis.In this regard,this study focuses on the seismic responses and fragility of liquid storage tanks.

Reinforced Concrete Water Tank Design Requirements

Reinforced concrete water tanks are constructed for storing water.The design of reinforced concrete water tank is based on IS 3370 2009 (Parts I IV).The design depends on the location of tanks,i.e.overhead,on ground or underground water tanks.The tanks can be made in different shapes usually circular and rectangular shapes []Process Industry Practices Structuralthe tank settles.4.2 Load Types and Applications Tank foundations should be designed for the following loads and forces where they exist.4.2.1 Dead Load Dead load is the weight of the metal (shell,roof,bottom plates,access ladders,platforms,nozzles,manways,roof support columns,etc.) 4.2.2 Product LoadPreventing Tank Flotation PetrolPlazaAn empty,air tight bottle will float on water.If forced under water,it will rise to the surface when the downward pressure is released.An underground storage tank submerged in a flooded excavation reacts the same way,except it contains a greater volume of air and exerts much more up-ward force.Even tanks partially filled with product may
