Not sure where to actually post this, so here it goes. I have a project that is 5-story with a combination of concrete podium and 4-stories of wood. The 4-story wood structure is Type V, and the concrete podium is Type I. The issue is the 5-story structure has a base footprint of...

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...

What are the limits for members for highway transportation? Maximum length and height prior to requiring the over length transports ect.

I didn't even know that site existed. Thanks a lot.

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.

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...

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.

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...

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...

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...

Do you weld the bolts to t he frame, or do you offset and thru bolt it? Do you add stiffeners at the hold-down?

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...

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...

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...

I have a soil report that recommends a 'California' style slab, or a waffle slab. Now, I am very familiar with a waffle slab, but what is a 'California' style slab?
