what we usually do. A cantilevered wall in masonry doesn't seem to work
past about 12'. Even then you big huge footings.

would recommend using a double firewall in this instance.

had a brief search of the archives for this topic but had no luck in finding
have a situation where I need to design a firewall (not fire separation)
between an existing freezer building (steel frame clad with insulation
panels) and a new processing facility. the firewall will be constructed in
between the insulation panels of the existing building and the steel framing
of the new building.
The building is in Vancouver BC which most of you know is a high
seismic zone. The dilemma is how to connect the fire wall to the new steel
frame such that collapse of the building doesn't cause collapse of the
firewall and yet still support the wall by the frame and roof diaphragm
under seismic loads. Any magical connection out there that can achieve this?
My brief search of the archives returned some mention of melt-away anchors,
however, the possibility remains that the fire is remote from the wall (say
on the next row of columns parallel to the wall). This could still cause the
building to collapse without the opportunity for these melt-away anchors to
other question relates to the existing building. For those familiar with the
NBCC or BCBC. Does the existing building need to be tied to the firewall? My
understanding is that the intent of the code is simply to supply a wall that
remains standing in the event that either building collapses. In
essence, for the pure purpose of a firewall, it does not have to
be tied to either building, it can be free standing.
any assistance is greatly appreciated.
