COMPARISON OF SEISMIC BEHAVIOUR OF TYPICAL RC BRACED MULTISTOREY STRUCTURE WITH COMPOSITE STRUCTURE

ABSTRACT In this modern period, it is necessary to design the structure such that it is capable of resisting the lateral forces which are acting on it. There are several ways to make the structure seismic resistant. Now-a-days providing bracings to the structure has become effective as it resists lateral loads efficiently. Bracings frameworks are one of the horizontal load opposing framework which has auxiliary significance extraordinarily in high rise structures. Distinctive supporting frameworks are sufficiently proficient for seismic reactions. To know the significance of various propping frameworks in multistorey RC outline structure. The present study deals with the study of seismic behavior of 3 models with different types of bracings i.e X, V, Inverted V type and analyzed by dynamic method i.e Response Spectrum by ETABS programming .Results, for example, seismic base shear , story displacements, story overturning moments, story shear, story drifts and selfweight of the structure have been assessed and compared with bare frame model and composite structure. X braced model is indicating better seismic execution out of the considerable number of models. Key words: RC Structures, Composite structures and bracings
