Seismic Analysis of Elevated Intze Type Water Tank (original) (raw)

As known from previous occurrences, Elevated water tanks were heavily damaged or collapsed during earthquakes. This might be due to lack of knowledge about seismic behaviour of water tank or improper geometrical selection of staging patterns. The staging plays critical role in design of water tanks as in water tanks large mass is supported by slender staging. The main objective of this study is to understand the seismic behaviour of tank under various staging patterns using SAP2000 software. In this paper different staging patterns considered are normal hexagonal bracing, hexagonal and cross bracing and hexagonal and radial bracings.
