    CMU basement wall with unreinforced courses at top

    I have a situation where CMU basement wall at a residential porch was construction using 12" block with #5 bars @ 48" OC. There is a bond beam at the top of the 12" wall and then two courses of unreinforced 6" block aligned with the inside face of the 12" block which will be above grade and...

    Roof Top Condensing Unit Fastening to Structure

    In the midwest, we typically do this for small roof top mechanical equipment. Anchoring through the roof results in penetrations that are prone to leaks and require more frequent maintenance. I've never heard of one moving problematically let alone blowing off the roof or tipping over. Yet an...

    Hoop House Design

    I had a client come to me for structural analysis for hoop houses he's been building for nearly a decade with no problems. He will be using them in a situation where it will no longer be considered a temporary structure. Because of this the jurisdiction is requiring calcs showing it meets the...

    Wood Floor Trusses @ 12" OC?

    Does anyone here have experience using wood floor trusses at 12" OC? I have 26'-0" spans and the only way to get that to work with my depth restriction is 12" OC. I'm hesitant because I feel like it will make using the space for utilities very challenging - especially duct work. This is for...

    Heavy Moment Connections Due to Gravity Loads

    I am working on a 5 over 1 mixed-use building with a composite steel podium. the 5 stories above are CFMF. The bearing walls align with the column lines. The resulting gravity loads are very large and the beams are quite big: up to W40x211. The upper floor diaphragms span laterally to the CMU...

    Ledger or Hangers For Addition

    I am working on a residential addition. The new floor framing will be higher than the existing by about 8" to 12". If it wasn't, I would just remove the rim joist, run the new joists over the existing wall and install blocking. But I don't want to interrupt the sill plate. Would it make sense to...

    Underpinning wall hinge

    This is sort of a general question about underpinning. I see companies advertising underpinning like the detail shown below. How do they connect the underpin to the existing foundation to resist the moment? In general I'm curious how engineers detail similar scenarios so the new wall retains the...

    Residential Basement Wall Reinforcing

    I have a contractor suggesting my basement wall reinforcing is excessive. I'm sure it is in terms of strength but for temp and shrinkage crack control and meeting code I'm not so sure. It's a 12" thick wall (mainly for a 2x6 wall with a brick veneer. It's 11'-0" from top of wall to top of...

    Hip Roof Truss Layout

    1. When doing residential markups for an architect, how much information do you typically provide for complex hip roof truss framing when the trusses are delegated design? Design loads only? Design loads with common truss profiles (see fourth image)? Complete conceptual Layout? I figure, I'm not...

    Spliced Wood Stair Stringer at Landing

    I don't have much familiarity with wood stair design. The little wood design I've done, the stairs have typically been a delegated design. In the case I'm looking at now, I don't have support at the top of the stair run. So the stringer will need to span across the landing, to the wall (see...

    Improper Roof Shedding of Rainwater

    The 4 unit condo building I live in has a large flat roof (100' long by 40' wide). Water drains in one direction to a single gutter on the long side. This gutter then supposed to drain to a 3"x4" downspout on each end. It works properly on an identical building nextdoor. However, damage...
