General tips for Project review Steel frame

[Nicolas R.]

Hi All,

I am currently undertaking a peer review for a steel struture designed by another consultant. I will be focusing mostly on primary structure from serviciability and strenght requirements. The structure consist of a large span frames supporting roof subject to high wind loads, I am wondering if experienced engineers within the community could give me any recommendatons or tips considering their previous experiences with similar projects. Appreciate your interest in my post. Thanks.

Regards,
NRR

There are lots of things to check here, but at least two things on my list would be as follows:
1. Load path. Making sure that wind/seismic loads have a path to the diaphragm and that the diaphragm has adequate fastening to the lateral resisting system. Included in that would be diaphragm shear, making sure that if collectors are required that they are provided and the additional axial load has been accounted for in those members and their connections.
2. Uplift capacity of roof members. I have seen countless times where roof beams are not braced along their bottom flanges as required when considering uplift and the resulting compression in the bottom flange of roof beams.
