Abstract:

In this enchanting world of structure design, building with new innovative ideas most of the time it is with the sky touching height. As these structures are extended vertically they are going to with stand the lateral loads in an enormous intensity. In this paper an investigation has been carried out over a 40 storey RCC structural space frame using different lateral load resisting system used in tall buildings. These structural systems used in the study are “shear wall”, “outrigger” and “dia-grid”. Analysis has been carried out using different method of analysis for static earthquake forces, dynamic earthquake forces (response spectrum analysis and time history analysis performed under the guidelines of IS: 1893-2002 and IS: 800-2000 respectively) and static wind forces. This will help to understand the behaviour of the mentioned lateral load resisting systems under dynamic load effect. The basic modelling technique and assumption are made by using ETABS 15.2.0 and other consideration are made according to the Indian Standard. A comparison of the top storey displacement, storey drift of the frame and the time period of the whole structure is done for different configuration of lateral load resisting systems. At the completion of the study the conclusion will be arrived and stated regarding to the effect of seismic load application.
