Thanks for all of the help. I have an appointment with a structural engineer who will analyze and detail a correction.
I will also direct his attention to another staircase I've become aware of, which has full thickness rust penetration on at least 2 surfaces of a box beam. I had no luck...
I'm not sure, somewhere on the order of 8-12 treads.
I'm pulling the pictures down since i have the answer I needed - that it is worthy of bringing to the attention of a dedicated structural engineer, and that's what will be done.
Thank you all.
I believe the staircase is steel and not aluminum. To my knowledge we don't use aluminum at all in our facility, we use either powder coated soft steel, stainless or some other type of steel.
I don't feel I'm qualified to do a proper analysis or detail a modification. I checked and we don't have a structural engineer on staff, but contract with a local structural engineer for designs requiring a stamp. I've contacted a site manager and Monday we will be contacting that engineer to...
No, this facility is not involved in structural design or fabrication at all. They manufacture a food product. I doubt if they even have a structural engineer or civil engineer on staff - they probably hire one only for larger building projects. This staircase probably resulted from Maintenance...
Yes, this is exactly my concern. This staircase sees what I'd guess is "moderate" use (like you said, probably not more than 2 people at once, on the order of 10s of trips per hour).
There is one platform above which is beam supported, and where the staircase stringer is connected directly to...
No, there is only one plate, which, bent different directions, forms both the kick-plate and the flange. It is just a single thickness of diamondplate.
I can get a better picture from the top, but my memory says the toe plate isn't connected to the stair stringer at all and the only support on...
I'm not sure what a toeplate is, sorry. Is that what I'm calling a flange? A bend in the diamondplate that sticks up some 4"?
The stair stringer is only attached to the diamondplate at bottom. The stair stringer at right is some 6" from the beam piece connected to the bottom set of stairs, and...
Unfortunately, I am describing the floor plate (well, landing plate) connection of the top flight of a stairs-landing-stairs assembly. So it's possibly worse than you're thinking. The stairs are supported stringer-to-beam at the top, and the staircase itself is standard metal industrial stairs...
First, I'm a mechanical engineering student, so I'm not familiar with the US building codes pertaining to this issue. This is also not coursework, but curiosity.
I have encountered a staircase in an industrial setting that is anchored at one end to diamondplate only. One side of the staircase...
