Analysis of Soft Storey Building with Different Types of Steel Bracings Under Seismic Load
Nowadays, open ground storey is preferred in multi-storeyed buildings due to increased traffic congestions, lack of availability of space for parking, etc. The open ground storey or soft storey buildings show a greater tendency to collapse during an earthquake because they possess discontinuity in stiffness, as one storey is significantly more flexible than the adjacent storey. Shear wall, steel bracings, floor diaphragms, etc., are used to mitigate the effect of soft storey. In this study, a seven-storeyed building is considered for the analysis. The building is modelled as bare frame, soft storey frame, and frame with steel bracings. The bracings used here are cross-bracing, concentric inverted V bracing and eccentric inverted V bracing to reduce the effect of soft storey. Linear and nonlinear dynamic analyses are carried out using ETABS 2016 software. The response of the soft storey building, i.e. storey displacement and storey drift, is found for each type of bracing, and the most efficient one is found. The same building model is used for both linear and nonlinear analyses. The response of the building model is also found in various seismic zones as per IS 1893 (Part 1): 2016, and the results are compared.
