DETERMINATION OF STRESS FACTORS OF A OVERHEAD CIRCULAR WATER TANK CONSIDERING AN AXISYMMETRIC ELEMENT

A large number of water tanks is being constructed around the world. The objective of this project is to analyze the circular water tank as a axisymmetric element. Circular water tanks are more efficient for larger storage capacities. According to IS code provision, water tank wall and base are acting separately and that the base is rigid and flexible. In reality the wall and the base are consider as a monolithic structure. In this work, axisymmetric analysis has been carried out to study the stress distribution in the wall and the base slab of the circular tanks. This papers involves study of water tanks models by two cases – 1. Conventional. 2. Reality. Conventional - ANSYS model of wall with fixed base was created and the results from the model found to be coincide with IS code 3370 coefficient. Reality - Based on the properties assigned in the previous model a new model is created in ANSYS considered the wall and base slab acts monolithically and the results from the model is not coincide with IS code 3370 coefficient. As the results both method were compared and studied.
