assessment of behavior of moment - resistant reinforced concrete buildings subjected to surface blast loads

In this study behavior of twO reinforced concrete buildings which have been designed in accordance to national building codes have been evaluated to surface blast loading the two buildings are modeled in 3D dimension in abaqus explicit software. The buildings under investigation include 4-storey and 8-storey moment resistant frames these two buildings are analyzed under surface blast loading and seismic loading then structural responses such as base shear and base moment are compared with each other.base on the responses it is concluded that blast has muchhigher effects than earthquake on the builings although time period of blast is much less than of earthquake.
