ThesisItem Open Access Seismic analysis of Intze water tank with different bracing configurations(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Agari, Chetan; Verma, V.K.Elevated water tanks are important Civil Engineering structure which is considered as compulsory town services in many cities. Due to storage of water, it can be used in essential requirements like drinking as well as quenching fires. In recent years, there has been an increased attention focused on the seismic safety of lifeline structure such as elevated tanks in seismic region. Many elevated water tanks suffered damage and collapse to their staging in earthquakes, therefore their safety performance is a critical concern during strong earthquake. In the present work, four brace patterns viz. simple brace, cross brace, rectangular brace and radial brace attached with different staging heights (15 m, 20 m, and 25 m) are analysed for seismic zone II, III and IV for tank in empty condition and tank filled condition. The most economical and safe, Intze type tank of 1000 kilolitre capacity has been considered. For the analysis of Intze tank, 72 models have been created using STAAD.ProV8i Software, in which 36 models are analysed in empty condition and another 36 models are analysed in tank filled condition. Every seismic zone has 12 models and each brace has three different staging rises. Various kinds of loads and their combinations are applied to all the tanks and response spectrum analysis has been carried out. Various parameters have been obtained for various brace system for their long time serviceability, stability and safety.
