Title

Study the progressive collapse analysis of shear wall-framed building with waffle and ribbed slab for different seismic zones factor

Abstract

The progressive collapse of the building occurs when one or more vertical load-carrying structural elements like columns and shear walls are removed. once a column is removed due to an extreme load generated either by natural hazards such as an earthquake or by manmade like gas explosions, terrorist attacks, impact by vehicles, etc. the weight of the structure transfers to neighboring columns in the structure. The present analytical study investigates failure criteria and the potential of structural collapse of irregular R.C frame building having waffle slab and ribbed slab with the shear wall. The column has been removed at one location and the spread of damage is evaluated. The progressive collapse study has been done by removing the column at an identified critical location as per GSA (2003) guidelines. Static analysis is performed using structural analysis program ETABS 16.2.1, For each case, the results have been taken in terms of demand capacity ratio (DCR) at critical sections, and thus, the structure has been assessed for it’s susceptible to progressive collapse. but the new version of ETABS 19 Enhancements provides the output tables that have been enhanced to tabulate the demand-capacity ratio (D/C ratio) for the whole model, as well as for each object individually. The results showed the existence of the column in the building makes it resistive to progressive collapse under the loss of vertical load-bearing element by providing sufficient stiffness and load paths for gravity loads.
