    What items can you seal as an Arizona PE

    I am a working structural engineer and originally licensed in Texas. I have passed the SE-1, so not considered a SE. I can’t be grandfathered into a SE in Arizona, nor licensed as an SE, so if I obtain a PE in Arizona does anyone know what I would be limited to sealing? In general, most of...

    SST Truss Tables

    SSTs are a little specialized type of wood trusses, so not really something you can call another wood truss supplier, like Alpine, for assistance. Thanks for the insight.

    SST Truss Tables

    Does anyone have the truss tables for the SST trusses by Standard Structures, Inc? They have since been sold, and their website is closed and all tables are gone. I have a lot of California renovation projects that use the SST wood trusses, so hoping someone was smarter than me and...

    Joist Direction

    If you have an equal bay spacing, which direction is the most economical way to frame your joist (parallel or perpendicular to the roof slope)? Basically, either your joist slope of your joist girder (or beam). I've heard cases for both, but curious of your thoughts.

    Out-of-Plan Seismic Loading on Masonry (CMU) Wall

    I have a load bearing masonry wall with a parapet. When determining the out-of-plane pressure on the wall I utilize ASCE 7-05, Section 12.11.1 (Structural Walls and Their Anchorage: Design for Out-of-Plane Forces). The argument arrived that the out-of-plane forces should be design per 13.3.1...

    Existing Open Web Joist

    I am trying to figure out the configuration of an existing joist. It does not seem to fit the configuration that would help me determine the proper designation as specified in the 75-year Steel Joist Manual. Does anyone have any other suggestions to determine the proper joist callout? What I...

    Mechanical Screen Design

    I have a tall mechanical screen that will be constructed on top of the roof. There is a small gap seperating the roof and the screen. I am designing it as a parapet, but the wind load is very large. I am looking if there is a provision that would allow to design as something besides a...

    Wood Shear Wall on Moment Frame

    If you have a multi-story, primarily wood structure, with shear walls bearing on a steel moment frame. How do you typically transfer the shear wall forces to the moment frame? I have heard of different methods for this connection, but would like to get a broader idea of the construction...

    Lintel - Supporting 12" Masonry

    The lintel itself is interior, but half way up the wall it becomes exterior. While possible, I think I can get a deep masonry lintel work, I am hesitant with such a large span. I have never developed one for that type of span or loading, but I guess there is a first for everything. I have...

    Lintel - Supporting 12" Masonry

    I have a school with a fine arts building. It has an opening for the stage of 45’, and I need to design the lintel. The CMU above is a 44ft and I feel I can not do triangle loading due to the need of control joints. Also, it is supporting a fly-loft and roof, because I can not do the triangle...

    AutoCAD - Grid Lines

    My current firm uses grid lines that do not go through the entire structure. The generally stop the grid lines at the structures extent. In general, other places I have worked took the grid lines through the structure to pass through all columns on the grid line. While I understand the...

    RAM Advanse

    Have using a few programs here is my thoughts. STAAD is great, but to me the hardest to learn and utilize. It is very powerful, but not as user friendly. In my opinion, STAAD is best learned from people that use it everyday, and not through tutorials or manuals. RISA is probably the...
