HYDRODYNAMIC PRESSURE DUE TO EARTHQUAKE ( ON DAMS, CONTAINERS AND PIERS )

Abstract

This dissertation makes a critical review of the vari-ous methods, -analytical and experimental, for the determination of hydrodynamic pressures on dams, containers and piers due to an earthquake. A comparative study of all the available methods concludes that rierner and Sundquists approach to the problem is the best but for all practical purposes Housner's approximate so —lutions can be used safely without involving appreciable error. The experimental work conducted on an Electrical Analogy Tray apparatus for determination of hydrodynamic pressure due to an earthquake on eleven profiles of dams in 4' x 6" x 2" (deep) .tray, supports Zanger's work. It. is concluded that this method affords a very easy and cheap method for experimental determin-ation of hydrodynamic pressure 'distribution on a dam of any pro-file. for a two dimensional case only. Study has also been made to show that how the various assumptions of several approaches to the problem effect the distribution of hydrodynamic ,sure • The conclusions drawn from the critical study of the problem have been summarised in the end. In the case of tanks for a economic design in seismic region,. a open design is recommended. The recommendations of I.S.I. and U.S.B.R, have also been incorpor-ated in the end..
