Does anyone know how to apply the Partially Enclosed Criteria to an addition? Should the entire complex (see attached) be included in the determination of the classification or should the criteria only apply to the new construction? The given the dimensions of the addition and proposed 20'x7'...

Is it possible to place a fastener from the inside of the flange of a 3 1/2" cold formed C-joist section?

I assume if the contractor wants to be cautious he would use needle beams with adjustable shores to cut the opening and implement the new lintel, but there are other methods as well. I don't think that you can design the new structural elements without considering the alterations to the existing...

There are no known structural plans. Thanks EngineeringEric "keep masonry in compression" was what I was looking for sort of. I just thought that there might have been a standardized method out there. ASCE 7 - Appendix 11B is very brief, and the only thing I got out of it was that you can't...

I need guidance on the evaluation process of the "existing strength" because we are making alterations to it.

ASCE/SEI 41-13 Seismic Evaluation and Retrofit of Existing Buildings: I am doing the structural engineering for a new building adjacent to an existing multi-wythe church originally constructed in the 1920s. The two are linked by a connector. The impact to the existing church is minimal but...

The channels on the facade is the theme of this project, one because it's an addition so it has to match, and two because the architects want to add a ton more storefront and steel framing for a clerestory between the new and existing. So I guess the joist extensions are a small battle in a...

Yes, the joist seat is actually extended out over both channels to support 2'-6" of overhang. So you're saying that if both channels are attached then I don't need to worry about torsion being a problem?

The T.O. steel is bearing for open web joists with a metal roof deck.

I am trying to come up with a clever way to connect (2) C15X33.9 so that there is at least a 3" gap for insulation. The reason for this is that one channel is exposed and only for aesthetics while the inside channel is structural. The 3" gap is supposed to create a thermal break as required by...

Users of the imperial system of measurement. Is there a shorthand for the abbreviation (p.s.f.) pounds per square foot? For example, I can show that I'm using the unit of feet in decimal by simply placing a tick mark at the upper right, instead of (ft.) For the beam loading calculations, my page...
