PREVENTION OF BUILDING AGAINST PROGRESSIVE COLLAPSE: According to the modern scenario, most of the structures follow progressive collapse phenomenon. Even though buildings are designed to resist for all probable loads without any failure of structural member, they fail occasionally due to insufficient and poor design and construction techniques, especially for extreme and abnormal loads. This book deals with the analysis and design of G+3, G+ 5, G+ 7 and G+12 (with 10 different cases) storey buildings in SAP-2000 by performing Non-linear Dynamic Alternative Path Method. The variation of base shear and spectral acceleration and displacement of buildings along with deformations of the beams and axial deformation of columns over the height of the structure had evaluated & analysed and its effects on the load redistribution has also discussed, identified and characterized with the removal of column at various positions. The book will has immense benefit in structural designing of buildings against progressive collapse failure.
