Replacing main carrying lvl beams


per engineer's report, we have to replace 3 lvl ( 2 x 10 ) beams + 2 2x10's scabbed alongside as they've twisted a bit,,, we just installed 2' x 2' x 1' steel-reinforced foundations yesterday to replace some sort of apron/vest pre-cast ' thingie ' made to fit 6" x 6" p/t'd columns.

this is the main carrying beam for the house - we're using 4 lvl's - the engineer wants them bolted together w/1/2" bolts,,, he didn't specify carriage or other.

sound good ? thanks in adv !

You will not get anyone here to disagree with an engineer.

Each engineered wood manufacturer (iLevel, Boise, etc.) have their own recommendations for joining multiply members, especially when side loaded.

See who made the members and check out their website.

or ask the PE, after all it's their design.

Good luck!

always thought truss locks were something male athletes had to wear i shouldda thought to ask the lvl manufacturer fwiw, engineer doesn't return phone calls or answer e-mails,,, same w/selling broker & owner who's the seller have an idea he certainly deposited the buyer's check quickly tho

thanks guys - APPRECIATE THE KICK-IN-THE***

I am going to hazard a guess that the engineer is not under contract to you, but prepared the plans for someone else. If the plans fail to include a detail on connecting the LVL's, I would talk to to the building inspector first to see what they want to see. My building inspector loves Truss Loks, but some building inspectors do not know what they are, and will not approve them. Typically if using bolts, you will need to use standard steel bolts with double nuts to prevent loose nut syndrome. Some inspectors will allow use of a lock washer plus a single nut. A few may even allow use of Nylo nuts or perhaps Lok Tite. In the end it is the building inspector's call if the plans do not specify technique.
