EFFECTS OF SEISMIC ISOLATION ON TIME PERIOD AND STOREY SHEAR IN RC BUILDING WITH BRACINGS AND SHEAR WALLS

Raghunandan M H, Suma Devi

Abstract: Higher the time period higher will be the flexibility this helps in controlling the structural damages during ground motions. In a flexible building different parts move by different amount, but for a stiff building every part moves by same amount. Depending on the situation either a flexible or a stiff structure can be made to work. In this study the comparison of fundamental time period and storey shear between fixed base building and isolated base building is done by modelled in Etabs non-linear software with different frame systems and storey height in order to know the variation of time period with different conditions.
