Study and Analysis of Intz water tank with manual and software-based design with base isolation

The seismic response of an overhead water tank, cylindrical, extra-large water storage tank by using triple friction pendulum system is analyzed. Most of the overhead tanks have a fundamental frequency which includes a series of resonance of greatest earthquake ground motions. It is an operative way to reduce the response of an isolation system used for storage of water tanks under a sturdy earthquake. However, it is problematic to implement in preparation with common isolation bearings The research is directed with study of existing studies in the field of seismic behavior of intz water tank. Base isolation is one of the technologies applied to decrease the consequence of earthquake effect. The principle is to separate the base of the overhead water tank from footing ground. The problematic is taken as Intz water tank design to survive water tank against seismic accomplishment. three categories of base are used to analyses and compare overhead first is manual design of intz water tank with fixed base + response by SRSS and second case is intz water tank with fixed base by sap2000 and Third case with is intz water tank with triple friction pendulum on sap2000. The software SAP 2000 are used to assessment fixed and triple friction pendulum base intz water tank. It is primary period in India when overhead water tank is tested with triple friction pendulum isolation are analyzed for seismic zone V. It is initiate from results that deflection and base shear analyzed with triple friction pendulum are lesser than fixed base with outstanding margin and it is determined that study endorses use of triple friction pendulum base isolation for seismic zone V in India.


I. INTRODUCTION
Elevated Water tanks are salvation developments which are being constructed in growing numbers to store water for drinking purpose. The capacities of these containers are huge and have capacities of around 1800 mᶟ or it may be large depends on the population of that area. Elevated water tank consists of an RCC container or it may made up of steel tank, which contains the large amount of water, the seismic study of these structures is a difficult and thought-provoking task because the construction of the tank based on the with a smaller number of footing and column as compare to building and the soil erection contact must be considered. water tanks present an excessive risk if they were failed during an earthquake. Base isolation is a demonstrated knowledge for the seismic strategy of structures. The system diminishes the probability of structural and non-structural damage to a water tank exposed to seismic forces. By using base isolation, we can reduce the lateral forces and displacement of the structure which can damage the structure through earthquake. Due to which we can save the government property and water which get distributed to people.
However, in spite of base isolation's safety benefits, the technology is under operated. Although tall, flexible, and non-critical facilities such as office buildings are not the most ideal candidates for base isolation, they may still achieve an optimal seismic design by using the technology. Therefore, in order to increase the quality and prevalence of base isolated structures, there is a need to study the technology's seismic performance enhancements and cost effectiveness for projects on which the system is infrequently used.IS 1893:2002 is the code to design structures under earthquake zones. There are two major methods of seismic analysis which are 1. Response Spectrum Analysis: This Analysis is based on ideal predefined statistics which are not actual time data collected since actual earthquake in the part. Elevated water tank response and behavior is composed in real time and can be used to design future elevated water tank under seismic loading. Need of study 1.Baseisolation technique is newly isolated structure which is provided at the base of structure.it is only performed on building and hospital etc. None of the research is done on base isolation on elevated water tank. 2.So the approach is done on Base isolation for Elevated water tank or manual and software comparison.

II. PROBLEM DESIGN
The design of overhead Intze Water Tank is carried out using the manual and computer aided design software sap2000 Elevated storage reservoir. The design is carried out as per relevant analysis procedures combined with Indian Standard Codes of Practices. The water tank dome is designed by working Stress's method. The foundation forces at the level of safe bearing capacity are also evaluated The software also gives the shape description of the tank and keeping various constraints, one can change the governing constraint to get the optimum result and safe design with economy.      /dx.doi.org/10.22161/ijaers.5.10.18  ISSN: 2349-6495(P) | 2456-1908(O  The farthest leeward column will be endangered to the superimposed axial load plus Vmax given above The column on the bending axis on the permissible Stress's in the material may be enlarged by 33.33% for the farthest leeward column the axial thrust Vmax due to wind load is less than even 10 % of the superimposed axial load. -: the effect of wind is not critical for the farthest leeward column however, column is situated on the bending axis need to be considered to see  /dx.doi.org/10.22161/ijaers.5.10.18  ISSN: 2349-6495(P) | 2456-1908(O)

DESIGN OF BRACES
The bending moment m1 and extreme value in a brace is governed by step 9 tan(θ + 8 ) =  The seismic presentation of RCC structures earlier and after the application of flexibility and stiffness -based elements method is to be studied in the present project. In this study we are presenting isolation system as a substitute of conventional technique to get improved performance of elevated water tank through the earthquake. This section offers model geometry evidence, including items such as joint coordinates, joint restraints, and element connectivity. Analysis of intz tank is to be performed using Sap2000 for Zone-V. 2.after the analysis is done for fixed base intz water tank is compared with the manual result obtained from manual design and sap2000 design. 3.in this study we have found that base shear and displacement result are equal. 4.but we cannot go for the further manual design of base isolation. 5 So software design by using sap2000 we design structure and compare it with fixed base intz water tank. Total base shear at the bottom of staging by SRSS V = 1016.36 kN. Displacement of tank sap2000: - Analysis of intz overhead tank is to be performed using Sap2000 with base isolation for Zone-V. 2.we have used the triple friction pendulum isolator at the support at ground level 3.Response analysis is performed for the intz water tank and design is analyized. 4. So software design by using sap2000 we design structure and compare it with fixed base intz water tank and base isolation. Total base shear at the bottom of staging by SRSS V = 894.69 kN. Displacement of tank sap2000 with base isolation: - Base shear and displacement analysis are performed with manual and SAP both for both fixed and triple friction pendulum support. Intz water tank is never been considered under research by researchers with triple friction pendulum Also, Manual deign is not having option for defining base isolation, still we software defined triple pendulum support in sap2000 to compare with manual fixed base elevated tank.

Graph. 1: Displacement
Result parameter for fixed sap2000: -In the sap2000 with fixed base of intz water tank. We have compared the design. we have found Same base shear and displacement as compared to manual design of intz water tank.

Graph. 2: Displacement sap2000
Result parameter for isolated base sap2000: -In the sap2000 with isolated base of intz water tank. We have found that base shear has been reduced to 12.00 % as compared to manual and base isolation. And also, we have found that there is less displacement as compared to manual with fixed base.

V.
CONCLUSION Elevated Water tank is never been considered under research by researchers with triple pendulum isolator. The result which we have obtained for manual fixed base and sap2000 fixed base we found that design for base shear and displacement are quite same. But for the base isolation elevated water tank we have found 2% decrease in base shear and in the displacement up to 90% is decrease with base isolator Base shear of Zone V because of zone factor same for manual and fixed response reduction factor etc. while considering seismic analysis. And decrease in base shear for base isolation and displacement.
