Comparative Analysis between Bare Frame, Infill Frame and Braced Frame with Soft Storey
Abstract:
Masonry infill is used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. Steel bracings are used to resist lateral loads and lateral deflection hence control the damage caused by the earthquake. In some cities of India the first storey of the RC frame building open to generate parking space called open ground storey also termed as Soft storey. In this study, response spectrum analysis is carried out for bare frame, masonry infill frame and braced frame. A symmetrical frame building (G+5) located in seismic zone-V is considered for modeling of all 3 frames for all 3 type of soils. Modeling of infill is considered by ?Equivalent diagonal strut method?. Eccentric forward and reverse steel bracing is used for modeling of braced frame. Comparative study concludes that the masonry infill frames are best suited among all the three types of constructions in terms of material cost benefit added with better seismic behavior. Response Spectrum method is used for seismic analysis. ETAB 2015 software is used and results are compared.
