Analysis of Reinforced Concrete Framed Structure Subjected to Blast Load Using Sap2000

Abstract

Blast is a wave of exceedingly compressed air
spreading outwards from an explosion. Blast loading is the
result of an explosion where this refers to a fast and surprising
launch of saved energy. Some portion of the energy is released
as thermal radiation while the major component of the response
is coupled into the air as air blast and into the dirt as ground
stun, both as radially growing stun waves. Blast loading on
buildings can be from unconfined or partially restrained
explosion charges. In the present project, the main aim is to
analyze the response of reinforced concrete framed structure
subjected to blast loads, with external blasting stand-off
distances as 10m, 20m, & 30m and with different charge weights
as 100kg, 200kg, and 300kg TNT. shear wall techniques are
implemented to resist the structure using IS 4991:1968. Dynamic
analysis of framed structure is done by time history function
method using SAP2000 software and it also includes the detail
report on displacements, and story drift of structure.
