If not, I will check out the BCA (Building Code of Australia) soon and let you know. I will post in the AS/NZS code issues forum and see if someone knows. JAE, I am not really up with the current housing code provisions here, as I don't do any small scale residential work. RE: Torsion on LVL beam supporting brick DaveAtkins (Structural) 17 Jan 09 09:40 So the wood beam is simply not code-compliant. Also, section 2304.12 states explicitly that no masonry may be supported by wood.ĪCI 530, section 6.2.2.3.3 states the following: "Provide noncombustible lintes or supports attached to noncombustible framing over openings where anchored veneer is not self-supporting."
In the IBC - section 1405.5 indicates that masonry veneer must meet ACI 530. So that then raises the question of whether wood beams can support masonry veneer in the IBC. So as an engineer, you can go to the IBC as structurebeton mentioned above. Since you have a wood beam supporting masonry in violation of the IRC, your next step would seem to be to go to the IBC in accordance with IRC R301.1.3 where it states that "Engineered design in accordance with the International Building Code is permitted for all buildings and stuctures, and parts thereof, included in the scope of this code." But it explicitly says no to wood beams supporting masonry over openings. The IRC does allow masonry to be supported by wood such as cases where an exterior wall turns back over a roof (per IRC Figure R703.7.2.1). supporting masonry veneer over an opening per R703.7.3.) If you are designing strictly under the IRC, then it does appear that the LVL is a code violation (i.e. MMC Engineering RE: Torsion on LVL beam supporting brick structurebeton (Structural) Is this structure in a high earthquake zone? A 7.2 off the Kuril Islands, and a 6.8 near New Caledonia. There were two 6.8 or higher earthquakes on the Western portion of the Pacific rim yesterday. Should they ever try to sell the place with out a fix, they are going to take a much bigger hit if it is not fixed than nessing up the exterior look. With that amount of brick above, the owner better seriously consider adding a central column to remedy the situation. Was this a sudden condition or gradual? If sudden, was there a heavy snow that loaded the valley. It is also interesting to note that a valley frames into the center of the span too. Is the roof trussed, stick framed, or a mix? The effect of any girder truss or point load may have been omitted on the header, especially if this structure did not have an original engineer involved in the design. It looks like there could possibly be a large point load from the roof - maybe a girder truss if it is a trussed roof - at the center of the garage door header span.
