I am installing some lightgauge steel studs (architectural) on top of an existing gas station roof (exposed). My concern is corrosion of the cold-formed steel members and fasteners. The location of the structure is in Southern California, however it is inland and in a very hot and dry climate...
I am mounting solar panels on an existing structure that has 3 roof areas with distinct member sizes and spans.
Since I do not have the existing plans, I conducted a site visit to size the roof purlins and check the overall structure condition. I am finding 2 areas of the roof where the roof...
I've been assigned my first solar installation job to be mounted on an existing commercial building. I need to provide adequate framing for the solar panels however the biggest challenge I have on this job is that I do NOT have the original building plans.
What I know is that the building has...
I am designing ground mount support system for some solar panels. The client is suggesting to extend the columns of the structure to be used as foundation (basically flagpole, IBC 1807.3.2.1). If we went this route, we are going to use galvanized cold-formed steel members however I want to...
I am looking at a historic church - I believe the construction was in the the 1920s. In plan, the dimensions of this building are 40' x 90'. In the 90 ft dimension, the concrete walls are 20 ft tall and span the entire length with window penetrations at mid-height that are roughly 3 ft wide...
I am working on a project to convert a residential flat roof to a pitched roof. The home was built in the 1960's and some modifications were made in the 90's. There is no official building plan for this structure.
The existing flat roof is made up of 2x6 laid flat against each other...
I am working on a project to build a 50'x50' walk-in-cooler inside a commercial warehouse structure. The warehouse structure was designed in the late 1980's. The ceiling panels can only span 25 ft and thus I need to provide a support in the middle for the two joining panels. Not having the...
I am working on a project involving relocation of pallet storage racks. The issue is that the racks are not made by the same company and the existing tenants do not have information regarding structural properties.
I went to the site and field measured all the frames, beams, and base plate...
Are there any shotpins (or similar) in the market, with an available ESR report, to transfer seismic shear forces from shear wall (down to cold-form steel tracks) to concrete slab of self-suported structure?
What is the difference between a tek screw and sheet metal screw (sms)? Where can I find tabulated values for different pullout and shear strength values for tek screws with respect to size and gauge of cold-formed steel members it's driven to? Thank you.
I am looking at an INTERIOR light frame structure - self supported inside an enclosed commercial building. It has 4 walls and a ceiling/roof. The seismic loads are low and therefore the min 5 psf, per IBC 1607.13, governs for out-of-plane loads of the wall studs. My question is, do I have to...
