Abstract

Finite Element Analysis of the tall slender RC structure with and without outrigger system has been carried out to study the behaviour of tall RC structure in terms of time period, base shear, base moment, story displacement & story drift. Due to reduction of lateral stiffness with the increase in height of structures, outrigger system has been proposed in the present study to minimize the effect due to loss of stiffness. The three dimensional model has been considered and analyzed for the gravity loading, seismic and wind loading, for seismic loading both Equivalent Static Method (Static) and Response Spectrum Method (Dynamic) has been carried out, and in the same manner for wind loading both IS Code coefficient method (Static) and Gust Factor method (Dynamic) has been carried out, IS 875 part III has been used for wind loading calculation and analysis, and IS 1893:2002 has been used for seismic loading calculation and analysis.
