should be to create as much stand-off
distance between the air shock wave
and the building as possible. On
congested city centers there may be
little or no scope for repositioning the
building, but what small stand-off there
is should be secured where possible.
This can be achieved by strategic
location of obstructions such as
bollards, trees and street furniture.
Equipment Establishment of protective cowl for
machine tools
Energy networks Gas, water, steam installations,
electrical connections, elevators and
water storage systems should be
planned to resist any explosion affects.
The main control units and installation
feeding points should be protected
from direct attacks. A reserve
installation system should be provided
for a potential explosion and should be
located remote from the main
installation system.
General measures With correct selection of the structural
system, well designed beam-column
connections, structural elements
designed adequately, moment frames
that transfer sufficient load and high
quality material it’s possible to build a
blast resistant building. Every single
member should be designed to bear the
possible blast loading. For the existing
structures, retrofitting of the structural
elements might be essential.
