Abstract
Soft floor structure is a common element in high rise or multi-story buildings due to urbanisation and space occupancy constraints. Without taking into account the strength and stiffness contributions of the in-fills, reinforced concrete framed structures with infills are often analysed as bare frames. However, infill panels have a tendency to interact with bonding frames when exposed to significant lateral stresses, which might result in a load resistance mechanism that was not intended. Due to their soft storeys, these measures cause a reduction in the stiffness of the lateral load resisting system, making a gradual collapse in a powerful earthquake inevitable for such structures. Due to the concrete columnsinability to offer significant shear resistance, damage and collapse are most often seen in soft-story structures during earthquakes. In contemporary multi-story buildings in metropolitan India, open first floors are a common design element. As shown by countless instances of intense shaking during previous earthquakes, such qualities are particularly undesirable in structures constructed in seismically active locations. Since response spectrum analysis offers response to the applied loads and spectral conditions, it is selected for the study of the model. With the aid of the response spectrum approach, the performance and behaviour of a structure with soft flooring at various levels are the main emphasis of the present research. ETABS V.16.03 is used to study six distinct model scenarios for analytical purposes. Following IS 456:2000 and IS 1893:2002, a G+20 building with a straightforward square layout is taken into account.
