Comparative study of Multistoried Building with X & Inverted V Bracing

Abstract

The most suitable technique in order to increase the performance and the lateral stability of the RC Frame building situated in earthquake prone areas is the use of steel bracings. In this paper comparison of seismic behavior of G+15 multistoried building situated in zone 4 on medium soil has been carried out on 3 different models by installing different types of bracing i.e X bracing and inverted V bracing. The designed structure should have enough lateral stability in order to resist the lateral force during the seismic shaking, and the parameters such as the storey drift should be within the permissible limits as per the IS 1893-2016. The use of Steel Bracing in Reinforced concrete structure not only helps to reduce the lateral loads during the earthquake but also helps us to reduce the section size of the reinforced concrete structures. In this paper 3 models have been analysed- Model no 1 – G+15 building without steel bracing, Model no 2- G+15 building with X bracing, Model no 3 – G+15 building with inverted V bracing, All the 3 models have been analysed with the help of STAAD PRO V8i software and comparison between these models have been carried out based on 3 seismic parameters such as Storey Drift, Storey Displacement and Base shear.
