1. Comparative Study on Elevated RCC Water Tank with Different Shapes in Zone V

AUTHOR NAME : Seema Meshram, Dr. S.G. Makarande, R.K. Kakpure

ABSTRACT : In very severe earthquake regions, Elevated storage reservoirs (ESR’s) are amongst the most important structures for the residential & industrial livelihood of humans. In many major urban and rural areas, they form an integral part of the water supply scheme from supplying water for drinking, household use, industrial use, firefighting, etc. The ESR’s must functional even after the earthquakes, as water is required for our daily usage. The main objective is to carry out a comparative study of different shapes of Elevated storage reservoirs for Static analysis. This project also studies the hydrodynamic effect i.e., Impulsive and Convective pressure on ESR’s in static earthquake response with different shapes. For detail study &. analysis purpose, two different shapes i.e., square and circular ESRs are considered with the similar storage capacity, height, staging system, Importance factor & similar Response reduction factor, in the considered earthquake Zone. For this study, a very severe earthquake zone (Zone - V) is considered. The analytical findings are plotted in form of comparative graphs and tables to understand the severity of ESR’s with different shapes. After comparing the results, a considerable difference is found in axial forces in columns, the bending moments in column & beam, displacement of staging & horizontal bending moments in tank walls. Which will further help in consideration of design philosophy for the safer and economical design of ESR’s. Thus, the design of the tank can be more economical, reliable and simple.

2. Study on Seismic Behaviour of Multistory Building with And Without Soft Story Effect using Masonary Strut

AUTHOR NAME : Minal U. Pawar, Prof. M. R. Nikhar, Prof. M. M. Lohe

ABSTRACT : Construction of multi-story buildings with open first stories is common practice in India. This is an unavoidable feature and is generally adopted for parking or reception lobbies. Multistoried buildings with open ground floors are inherently vulnerable to collapse due to earthquake load. This construction is still widespread in developing nations due to the social and functional need for providing car parking space at ground level or at the intermediate story. The engineering community warned against such buildings from time to time it is also known as a weak story due to less substantial resistance than the above story or below. Along with gravity load structure has to withstand lateral load which can develop high stresses which leads to the destruction of buildings. In this paper, the R.C.C. building is modeled and analyzed in two cases. I) Model with in-filled frame single strut approach from 1st story. II) Model with in-filled frame single strut approach with soft story effect. Response spectrum analysis is used for analyzing building models in ETABS. The performance of the building is evaluated in terms of story drift, story displacement, and time period. It is found that the steel braced system significantly contributes to the structural stiffness and reduces the maximum inter-story drift, lateral displacement of R.C.C building. The results of different systems are discussed and conclusions are made.
