NUMERICAL ANALYSIS OF ELEVATED FRAMED STAGING SHALLOW TANK BY NEWMARK’S STEP-BY-STEP METHOD
Journal Title: International Journal of Advanced Research in Engineering and Technology - Year 2019, Vol 10, Issue 2
Abstract
Water tank is a life line structure, are extensively used in water supply facilities, oil, gas and nuclear power plants, for storage of variety of liquid material, e.g. Oil, LNG.Due to earthquake critical damage to elevated R. C. C. tanks are found. In the present work, a 50 m3 water tank has been analyzed for x-direction earthquake ground motion for fixed and an isolation system (Elastomeric bearing) is used to reduce the behavior of the basic response e.g. base shear, time period, tower drift, flexibility, of the elevated R. C. C. tanks. For solving complicated equation of motion for a coupled analysis a Newmark’s step by step iteration method is used. After detailed analysis of 50 kL water tank, due to isolation base shear reduced significantly and the sloshing displacement increases as compared to non-isolated tank, also increase in isolation period from 2 sec to 4 sec, base shear reduced significantly.
