Blast analysis of
pre-cast wall panels on the MSP office building
The
Members of Scottish Parliament (MSP) building is situated to the West of the main Scottish
Parliament building in Edinburgh and contains offices for the Scottish
members of parliament and their staff. The
granite-clad building varies between four and six storeys in height,
and has an in situ reinforced concrete portal frame supporting
pre-cast concrete vault units which form the ceilings and support the
floor finishes. Unusual windows, which contain both a window seat and
a stepped shelving space, project out
at different widths from the Western face of the building. The
dynamic response of the distinctive pre-cast concrete backing panels
for these window pods was examined in detail using LUSAS finite
element analysis to assess the likely peak deformations under blast
loading. These thin panels, which contain a large irregular
opening, needed careful reinforcement detailing to achieve the
required degree of blast resistance.
