Abstract
-Composite structures are known for two load carrying structural members that is integrally connected and deflected as a single unit. As we increase the height of the building, the risk of wind and earthquake pressure increases. Thus, a structure is more complex without using lateral load resisting systems. In the present study, typical 30 storied building composing of RCC sections and composite sections are considered along with lateral load resisting systems for both type. ETABS is used for analysis for the seismic zone V. Equivalent Static Method of Analysis and Response Spectrum Analysis Method are carried out and comparison is drawn for both RCC and composite structures based on parameters such as displacement, drift and base shear. majorly 8 different types of models are considered. The results show that the shear wall structure reduces the displacement greatly than bracing system. It is found that the difference in the percentage of displacement is around 20% to 25%. The overall analysis briefs that the composite structures are better compared to RC structure due to its reduction in displacement and increase in its stiffness. Key Words: composite construction, concrete encased steel, core wall, bracing system, shear wall, coupling beams.
