Abstract
Since the damage suffered by buildings as a consequence of explosions
usually affect the people inside them, it is important to take it
into account when performing consequence analysis. The aim of this
paper is to provide a methodology to estimate consequences to buildings
from pressure waves produced by spherical vessel burst. This is done
by combining characteristic overpressure-impulse-distance curves

Alonso, J., 2006, Characteristic overpressure-impulse-distance curves
for vessel burst, Process Safety Progress, 25(3): 250-254 with PROBIT
equations. The main advantage of this methodology is that it allows
an overview of all the magnitudes involved, as damage is shown in
the same graph as the overpressure, impulse and distance. In this
paper diagrams and equations are presented to determine minor damage
to buildings (broken windows, displacement of doors and window frames,
tile displacement, etc.), major structural damage (cracks in walls,
collapse of some walls) and collapse (the damage is so extensive
that the building is partially or totally demolished).
