Paper Title
Impact Assessment of Bracing, Shear Wall & Dampers on Rcc Building Structures Under Blast Loading
Abstract
The amount of terrorist action such as blasts has amplified concern around the building safety. So, it is
becomingas the essential to design the building for blast loading also. In our study we compare the responseness of the bare
frame building with 10 storey under the action of surface blasts loading and when the building structure is modelled with
XBracing, Shear Wall and Viscous Dampers. In order to analyse the building structure under blast load one requires a in
depth knowledge of blast load phenomenon. The required blast load was determined with thehelp of IS 4991 -1968, Wu and
Hao-2005. In this paper we modelled a numerical problem of the fictive building structure which exposed to the blast
loading. The blasts sources effect of 1000kg weight is considered for standoff distance of 20m. The load for this analysis is
calculated with the help of codes and papers and it is applied as the nonlinear pressure-time history graph for the model
which was created using SAP2000. The result illustrates that thestorey displacement andstoreydrift for the modelled10
storey bare frame was identified to be greater as when compared with that of other models where addition ofbracing, shear
wall and dampers are provided. Whereas, in case of base shear and natural period it is vice versa.
