Performance Evaluation of RC Framed Hill Buildings with and Without Shear Walls
Buildings built on hill slopes demonstrate distinct seismic behaviour than conventional buildings resting on a plain ground. Due to asymmetric elevation and plan, irregular buildings exhibit variation in mass and stiffness at different floor levels, leading to the development of additional shear forces and moments in the frame members apart from lateral loads. It has been observed that the shear walls impart restraint to the extensive damage in buildings during earthquakes. The position and form of shear walls play significant role in structural performance of the building. Thus, in present study, the effect of shear walls on the seismic performance of two hill building configurations was studied. Both stepback and stepback-setback hill buildings have been modelled with shear walls at three different locations, viz. at corners, at mid-edge and at the centre of building. The finite element models were analysed using both equivalent static as well as response spectrum methods, and the dynamic parameters have been presented and compared in terms of fundamental time period, storey drift, storey shear and shear forces induced in the columns at foundation level in buildings. Further, for better comparison and suitability of position of shear walls, the total concrete volume and number of shear walls were kept equivalent in the respective geometric variations as well as in different direction of hill slopes.
