RE: Firewall Connection

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Can you send a copy of these ceramic bolts my way.

Also Heckman Building products makes a Zinc Alloy Breakaway Fire anchor
with a melting point of 786 degrees. They look like your standard masonry
tie. Why not tie the wall to both sides and one of the walls will always
remain standing.

Thank You

Use Nylatron (composite ceramic compound) fusible bolts.

Send me your fax number and I'll send you some info

      Subject: Firewall Connection

      Hi Folks,

      I had a brief search of the archives for this topic but had no luck
      in finding any assistance.

      I 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

      My 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.
