A concrete pedestal is a compression element provided to carry the loads from supported elements like columns,statues etc.to footing below the ground. The allowable bearing stress depends upon the ratio of column contact are to pedestal gross area.The ratios of contact area to pedestal area in different conditions are shown in below graph.The Study of Seismic Response on Accelerated Contained Jan 01,2017 ground supported tanks maximum slenderness ratios#0183;In this study fluid filling of ground-supported cylindrical rigid tank is analyzed.The characteristics of fluid filling are H = 2 m and R,inner radiuses of cylindrical tanks,where R depended on tank slenderness parameter [gamma] = H/R.For the tank slenderness parameter [gamma] = 0.3 is the inner radius of tank R 6.667 m,Tanks L/d Ratio - Industrial Professionals - Cheresources Sep 24,2009 ground supported tanks maximum slenderness ratios#0183;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? AWWA D100 or API-650 gives option for both ratios.

A higher slenderness ratio means a lower critical stress that will cause buckling. Conversely,a lower slenderness ratio results in a higher critical stress (but still within the elastic range of the material).Column sections with large r
