    Old Multi-Wythe Brick House

    Yes the new wall that is replacing the old wall is supporting the existing roof under the overframing which will take shear and will be designed accordingly. Getting a good connection from existing old hollow brick is tricky as well. I know hilti has some good products(HY-270) for this but I am...

    Old Multi-Wythe Brick House

    Looked at a possible project of an addition to an old 2 story multi-Wythe hollow brick home with a wood floor and roof. It’s a simple rectangle structure with a hip roof. Architect wants to demo one side of the house and attach a small 2 story addition to it. The addition will be wood with...

    Thrust on a Scissor Truss

    In a perfect world I could ask the architect for a bunch of items but I already know the answers...no chance on dropping the bottom chord. Rear wall has large windows and they are set on this ceiling pitch. The rear wall was a whole other back and forth with the archy which we won so going back...

    Thrust on a Scissor Truss

    Talked to the truss guys....increasing the depth of the truss a bit and going with a 2x6 bottom chord gets us to <0.5" horizontal deflection. Not a truss guy but surprisingly just going with a 2x6 btm. chord doesn't help with the deflection due to the reduction of webbing when going with larger...

    Thrust on a Scissor Truss

    Horizontal deflection in that scissor truss is 0.8"(live load deflection plus creep component of dead)

    Thrust on a Scissor Truss

    The beam is about 24' long but the upper ridge carries further toward the front and the ceiling profile changes. No chance the architect is going to allow a support in the middle of his great room. Design already changed from typical conventional framing, ridge beams, king posts, ect. where the...

    Lintel Required?

    That is ugly.....square it off or rip the brick off down to about mid height of the door for a skirt look.

    Thrust on a Scissor Truss

    I have a scissor truss bearing on a 2nd Flr. wall that is being supported by a stout LVL(sketch attached). I know they typically run these trusses with a pin and a roller which will give you a horizontal reaction to satisfy. The supporting walls are both dbl. 2x6's at 16" o.c. (for brick veneer...

    Multi-ply Sill Plate/6x6 on Top of Tie Beam

    Original Conventional framed roof damaged beyond repair so it is a complete tear off and they are going back with trusses. Contractor wants to avoid adding extra course of block because its a different sub then the framer who will more than likely install the plates and bolts. All thread rod...

    Multi-ply Sill Plate/6x6 on Top of Tie Beam

    Contractor needs to put a new roof/trusses on an existing CMU structure with a continuous reinforced tie beam at top of the bearing walls. He wants to raise the new ceiling/roof about 6" above the existing tie beam. He doesn't want to add an additional course of block but he mentioned installing...

    Main problems you encounter as a structural engineer

    Agents make more $$$ per building with much less risk but there are also alot more agents than structural engineers. They dont get a pay check every week and have to grind there arse off (on the weekends too) to make there 3% (6% is what the owner pays and the listing agent has to split it with...
