Description
Summary:Fire accidents in building structures are becoming frequent, forcing architects, structural engineers and MEP consultants to implement fire-curbing design measures. The current study deals with assessing the structural and economic impact of implementing fire rating requirements as per IS: 456 (2000) and National building code (NBC) (part 4) 2016. The analysis is carried out using ETABS by modelling a 5 storied building with a moment-resisting system. The base model after analysis and design is subsequently modified for fire ratings of 2hr and 3hr to suit the corresponding minimum requirements of cover and minimum dimension as per codes. The models with higher fire ratings will result in a heavier structure causative of two factors: the larger size of the members on account of minimum requirement and the requirement of a larger supporting structure (columns and beams) to sustain increased dead loads. The weight and time period indicative of the cost and dynamic properties of the resulting models are compared for each fire rating.
