A STUDY ON 80 M STAGING ELEVATED WATER RESERVOIRS

Elevated service reservoirs (ESR) are structures intended to accommodate water at a predetermined height. structurally, a water tower comprises of tank,support and foundation. A structure consists of a series of connected parts used to support loads. Some of the elements composing a structure are slabs, beams, and columns. The present work is concentrated on two major aspects relating to dynamic analysis and design of elevated Water reservoir for critical basic wind speed of 230 Km\hr. The first part of the present study has been focused on the development of general program to the wind load calculation of the structure at different heights using MATLAB and attempt has been made in the second part of the work focusing the best possible reservoir for a height of 80m Stage of 5 Lakh liters capacity in different load combinations. Different types of Reservoir like circular with bottom dome Tank, Intze Tank and Conical Tanks have been used and its efficiency has been studied. The modeling and analysis have been done using the STAAD pro. They have been studied for different parameters for a particular capacity of the water tank. Apart from structural safety and viability the economic aspect has also been looked into, which is very much important in the civil engineering field. The present study suggests that the choice of a particular reservoir is definitely depending on the configurations of the structure. A judicious choice can be made after taking this kind of analysis, which results in the optimization of the resource and ensures safety as well.
