    Snow Drift Load on Adjacent Sloped Roof

    HTURKAK, that's the section I'm seeing, but it's specific to the unbalanced loading. I know from an engineering standpoint it makes sense that it also applies to the drift, however I'm trying to think like a code reviewer that would say "but this exception doesn't specifically say it applies to...

    Snow Drift Load on Adjacent Sloped Roof

    We are designing a new 70' tall building adjacent to an existing 2-story house. The edge of our new building is about 4' from the existing home (physical gap between the buildings), and nearly 50' higher than the eave height, so it is well within the requirements of ASCE 7-16 section 7.7.2...

    Snow Drift on Adjacent Building with Separation

    I have a new, taller building being constructed next to an existing building with about a one foot separation. I know I need to check for snow drift on the low roof. I am using ASCE 7-05 for the drift, and due to the separation I can reduce the drift loads on the lower rood according to section...

    Dowel lap length too short

    I've never calculated development using section 12.2.3 (ACI 318 05) before. I always just used the equations on the table above that. Wow, that can make a huge difference! I got my wall reinforcing to work by a lot, and the pier reinforcing is right on to what it needs to be (33" for a #8 bar)...

    Dowel lap length too short

    I have an issue on a job site where rebar dowels were fabricated too short, therefore not providing the required lap length with the vertical reinforcing. One situation occurs at a basement wall for the reinforcing at both faces, and another occurs at column piers (steel building with concrete...

    Bracing of deep foundation elements - Pile

    Per IBC 2009 Section 1810.2.2, deep foundation elements (piles in my case) shall be braced to provide lateral stability in all directions. It goes on to say 3 piles in a pile cap provide this bracing, etc. That's fine, and I'm used to doing that for building foundations. Now, I will be designing...

    Specifying Structural Stainless Steel

    I am specifying and designing stainless steel in an ornamental stair. Per the architectural requirements, the stringers are to be stainless steel tube members, currently detailed at 12 inches deep and 4 inches wide (subject to change per my design). I've seen that ASTM A 276 appears to be the...
