Analysis of Retrofitted Cold Formed Steel Multistory Building Frame

The cold formed steel section are increasingly used as a structural elements in low rise buildings recent times, due to the advantages like economic production, easy transportation, labor cost and high strength weight ratio. In current work G+3 storied building frame is studied for seismic wind load using Staad-pro software. Light gauge taken beam slab elements. analysis carried out by Equivalent static method. After results such story displacement, drift, Base shear time period compared different models. also analyzed load. cross bracing element retrofitting technique. retrofitted loads obtained period, storey drift base values with corresponding of frame. showed shortening displacement X&Z directions indicating increased ductility, Stiffness structure. Hence proposed technique could be believed achieve success ductility required loading.
