When you make your permit application the plans examiner will confirm the adequacy of the structural design provided it is based on the tables in the Code. 5-do not drill, notch, cut or alter global lvl except as approved by lvl global inc. ![]() Of course the posts need to be supported on pad footings and you will likely need to provide a one hour fire separation between the garage and the suite above, including any walls and columns supporting the floor system. You would then need to go to a supplier of these materials and they would prepare a computer engineered design and also calculate what's needed for columns and footings. an LVL beam as suggested) the advantage with engineered lumber is it is much stronger and straighter than dimensional lumber but much more difficult to nail into. Alternatively you could use engineered lumber (i.e. The beam you describe is well within the allowable spans as per Table A-8 (built-up beam supporting not more than one floor).Īs long as you stay within the span tables in Part 9 of the Code there is no need for engineering. Just my opinion but with a building complicated by the large dormer and other gable I think you really need to someone capable of bringing the whole design together especially considering the typical dollars spents on these buildings.Hi Jonathan: The 2014 Alberta Building Code (current code) includes span tables for dimension lumber beams. With the floor system you still have a lot of pretty straight forward options as noted by many.Īnd as others have said be aware of any code issues/inspections so you don't cause yourself anymore work than you have to. With that large a dormer you are have gotten away from the gabled roof rafter/ridgeboard system with its "kick" that I mentioned earlier though you will still have that in certain locations away from the shed dormer. Looks like you need someone with knowledge to layout and size the roof framing that is required with a dormer that size (ridge beams, king trusses, posts, ect). ![]() If that is still the case the more I look at it the more it looks like it is not for the do-it-yourselfer to layout and size the roof. I didn't pick-up on the fact that you are going with the optional dormer shown and didn't realize the eave of the other gabled roof is at a different height than the main building - what else is new - lol. Brochure - This 2-page brochure contains primary information about West Fraser's LVL product line. If you do not know what intumescent fireproofing is, it is expensive compared to "high temp" RTV silicone.Ĭheck local codes for additional requirements. US Users Guide - This guide contains load tables, design properties, connection details, bearing details and allowable holes for West Fraser 2.0e, 1.9e and 1.8e LVL. All mechanical, plumbing and electrical penetrations must be sealed. Check Details Span beam lvl beams laminated timber glulam calculator lumber veneer deck hyne tji. My city requires 5/8" type X drywall on the bottom of floor trusses in a basement for fire code. ![]() If floor joists are not continuous above the beam, take the sum. Others have no additional considerations. Table is based on continuous floor joist span and simple or continuous beam span con- ditions. Others require 5/8" type X drywall on both sides of the web. Some places around here will not allow TJI floor construction at all. Lots of different building codes and interpretations. These tables provide maximum spans for the 2 grades of four common species of lumber (Southern Pine, Douglas Fir, Hem-fir, and Spruce-pine-fir (SPF). They are there to contain the blaze and keep it from spreading. Use the span tables in the links below to determine the maximum allowable lengths of joists and rafters. Some local fire departments will not enter a TJI or truss framed structure if danger to human life within the structure does not exist. These engineering marvels will span great distances compared to plain lumber, but the only thing holding them together is glue and metal splice plates.Ĭonventionally framed floors will stand for a virtual eternity in a fire compared to an unprotected truss or TJI floor. The big issue with I Joists and trusses is fire resistance.
