Abstract

In general the overall response of a building subjected to lateral loads like wind load and earthquake load increases with the increase in height of the building. Lateral load resisting systems are usually provided to reduce or decrease the load effect. The resistance may be offered by Frame Action, Core Walls, or combined Walls and Frames (also known as Dual System). In this study, 3D structural modeling based software STAAD. Pro V8i will be used to generate and analyze three-dimensional building models for the assessment of the relative effectiveness of the lateral load resisting systems under the effect of wind load and earthquake load and the maximum lateral displacement at the top storey is checked. The purpose of my research is to compare the stiffness of different structural framing system. Also to find out if we can neglect the presence of walls (concrete or masonry) if they are together with the frame system, where the frame system resists all the lateral shear forces and the walls will be considered just to bear the vertical load, and what are the provisions for these walls and their effect on the frames load. Ten types of RC frames including a bare frame, frames with external infill of 230mm thick, 150mm thick, 115mm thick and frames with both internal and external infills of 115 mm and 230 mm respectively with and without Staircase and Core wall have been considered. Number of storey has been G+29. Each model has been analyzed for the calculation of lateral displacement at the top story. From the study conclusion has been done in the frame analysis considering the stiffness of different elements i.e. staircase, core walls and infill walls which shows significant variation in the lateral displacement and graphs have been plotted.
