Earth quake analysis of structure by isolation technique in E-Tabs

Earth quake analysis of structure by isolation technique in E-Tabs

Dodda Harika, DV Bhavani and N Siva Prasad Rao
The base isolation is technique that has been used to protect the structures from the damaging effects of earthquake. The installation of isolators at the base increases the flexibility of the building structures. The aim of this research is to study the seismic behavior of different structures under fixed condition and base isolated condition. In present study Modeling and analysis of G+5 storey RC building is done in ETBS software for two cases. The first one is fixed base and the second one is base isolated. The Lead rubber bearing (LRB) is designed as per UBC 97 code and the same was used for analysis of base isolation system. Lead rubber isolator are provided to both the structures and then analysis are carried out for both fixed base and base isolated buildings under zone II and soil type II i.e. medium soil (according to IS 1893(part 1):2002). The results obtained from analysis were Storey displacement. Storey shear, storey acceleration, and Inter storey drift. Due to the presence of isolators the inter storey drift, storey accelerations and storey shear is greatly reduced and storey displacement is increased in both X and Y directions compared to fixed base structures.
