Compact Analysis Tool For Checking The Collapse
Dynamics Of Buildings

Abstract
The demolition of a building by explosives-induced rapid collapse is a design
problem which admits many solutions. Which arrangement is the best? When
addressing such a problem, it is useful to have a numerical model of the process,
which can be run repeatedly with different settings, allowing design alternatives
to be explored. The paper introduces one such numerical tool, which is compact,
and therefore inexpensive to run. The building is divided into blocks bounded
by the blast storeys. The model performs a time-integration of the equations of
motion in two dimensions, using two degrees of freedom per moving block. The
elements blasted-out storeys are removed at the timed delays. The remaining
elements in the blast storeys are given elastic properties at first, then plastic
properties, and finally f
