Effect Of Variation In Geometry & Seismic Zones On Rcc Elevated Water Tank: A Dynamic Analysis
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 6
Abstract
This research work provides an idea of effect of height to lateral dimension ratio on dynamic behaviour of reinforced cement concrete (RCC) circular elevated water tank. The various load intensity and structural parameter are calculated using reference from EQ 08 guidelines as per IS: 3370 (Part-II):2009 and IS: 3370 (Part-IV):1967. Analysis of elevated water tank is done using Response Spectrum Method and Wind Analysis. The considered elevated water tank models are studied for different seismic zone i.e. Zone-III and Zone-V as per IS: 1893 (Part-I):2016 and wind analysis is carried out as per IS: 875 (Part-III): 2015. The circular water tank is modelled and analysis is carried out in STAAD Pro. Result are obtained for the various height to diameter ratio as Tall and Broad elevated water tank in the form of lateral displacement and base shear. It is seen that if height to diameter ratio increases then, the effect of wind load appear in critical load combination for Zone-III. And for Zone-V seismic loading condition would be a part of critical load combination for lateral displacement. Base shear is increases with height to diameter ratio increase and also for the higher seismic zone.
