Abstract

This study simulated underground circular cylindrical shell structure to serve as water reservoir under known soil characteristics and conditions. Cognizance of prevailing acute scarcity of portable water supply, more often than not, during each year, this structural facility was also simulated for study under two distinct situations namely: when it is empty and when it is full of water. Structural analysis of the facility was carried out using the initial value model whereas the classical model served to establish validity. The study sought the stress effect arising from: empty condition and in full of water, on this facility. The investigation result revealed: Both classical and initial value models led to identical results. Effect of stress which resulted from the two different conditions did not diminish the structural integrity of this facility.
