Abstract: RC structures on sloping ground take columns of different height within one storey. Brittle shear failure is generally observed in short columns of RC frame as it takes the maximum shear during severe dynamic excitation by earthquake forces. Hence due to this immense problem, it is important to investigate practical and effective methods to rehabilitate these columns and the building as such. The objective of this research program is to assess the performance enhancement of short columns when strengthened with shear walls at specific locations of RC frame and with bracings exclusively. The strength attained with these two methods has been compared with one another assessment where most of the columns of RC frame are moved outside to the periphery, transforming the traditional grid of columns, which might demand the flat slab on each floor. It is possible that all the three might provide Solution for improvement in strength and stiffness of short columns of an RC frame on a sloping ground, but then these methods are compared and the one has been suggested which is cost effective. For this purpose 6 RC buildings are taken into consideration to carry out this research program, 3 on flat ground and 3 on sloping ground, one regular and one setback for each of the cases of ground geometry considered. The slope of the ground is taken as 16 degrees. Using Staad Pro v8i, the Response Spectrum Method for linear and Time History Analysis for non Linear dynamic analysis of these buildings can be done, to investigate various dynamic response characteristics and the respective strengthening technique can be applied and suggested as such.
