Progressive Collapse Analysis of T shape RCC Building

Abstract Structure collapse, on the other hand, is a very complicated phenomenon involving considerable nonlinearity and variety of mechanical interactions. It should be thoroughly examined through experiments numerical simulations to prevent occurrence from occurring. When initial local failure small portion structure takes place it leads spread that damage neighbor elements in chain reaction manner. Finally, collapse place. This known as Progressive collapse. progressive when vertical load carrying members such columns failed due manmade or natural accidental loads. Therefore this study analysis building carried by removing columns. In different column removal cases are considered. As per GSA guidelines, Demand Capacity ratio(DCR) beams calculated. From DCR value Evaluate stability against present “T”shape considered which consists 11 storey with bay sizes 4 meter X Y direction, height every 3 meters plinth floor assumed 3.5 meters. The measurements fixed throughout storey, but dimensions decrease rises, therefore have geometrical irregularity. loading calculated accordance G.S.A guidelines. design was created using ETABS software I.S 456-2000 code. Different parameters Demand-capacity ratio, Dynamic factor, Interaction Axial Force, Bending moment discussed.
