I am currently working on a facility that was constructed in 1968 on a naval base and it refers to "22Y Structural Steelwork" and "13Y Concrete Construction" as governing codes. There isn't any other reference to other building codes, but it does list material codes, such as ACI, AISC and ASA...
I'm working on a house where I have a 4:12 roof pitch and 12 feet tall walls. Now, when I'm checking my wind loading for the MWFRS to design my shear walls, I'm getting a positive pressure on the walls and a negative pressure for the roof. When I've had this situation before, I've always just...
That was it, just a new version of what I needed. I actually was able to get the information from the manufacturer. They said that each joist is made job specific (so why are there load tables...) and they were able to get the information I needed.
Thanks for the help!
Thanks Mike. I have hopefully made a little progress with this. I was able to speak with someone who said they can try and find the file if they had the property address and so on...Hopefully that comes through...
I'm wondering if anyone has any information regarding trus joist products from the early 70's. The architectural drawing date is 1971 and I'm looking for an L-series joist (2x4 wood chords, 1" diameter pipe webs). The earliest information that I have is from the mid-80's and I'm not sure if...
Thanks again for the responses.
@dvd: The guardrail will be welded in the field - that seems to be typical procedures for any of the fabricators we work with. Due to the width of the flange I can't really get a bolted connection in there that would be sufficient to resist the moment, but I...
@Paddingtongreen
Sorry about misspelling your name in the above post.
I also meant to ask about your response, because that confused me a little bit. I know the stress in my pipe, but I'm confused on how multiplying it by the thickness gives me the load per unit length.
Unfortunately I have...
Thanks unclesyd - I downloaded the demo of the software and was getting the same results that I was getting by checking it by hand. I'll have to check out that book and see what they have to say.
@Paddintongreen: Basically what I was doing was using the ole T=C=M/d. For my "d" distance I was...
Thanks for the input connectegr!
We're actually using a C12x20.7 so we have a 3" flange, which is good. I have checked it based on finding the centroid of each side and going from there and found that for this case a 3/16 inch fillet works. My concern is that I have to submit this to an EOR...
I'm looking for an accurate way to check the weld between a pipe and the top of a C-channel stringer. This is for a guardrail system and the pipe is assumed to have a fixed base (I don't know how else to get it to work otherwise). I know that when contractors are doing this type of connection...
Thanks for the input!
We have fillet welds for this area - 3/16" for this connection.
I'll also make sure that the surface of the beam (and column) are inspected thoroughly. That was really my big concern with them possibly torching it (what kind of swiss cheese beam and column would I then...
I have a client that placed a beam in the wrong location. It's only 1" - 2" away from the right location, but I'm a little concerned about them trying to torch off the old weld and re-weld 2" away. Is this a valid concern or am I just being overly worried about something that wont' be an...
Okay, so I think I have some of my confusion with the DDM answered. I have two points that I need clarification on though.
1. DDM says that live load must be no greater than 2x dead load. I have a fluid load (a pool filled with water) which isn't really either a dead or live load, but I...
I have a situation where I have a client with a pool that is proposed to be supported on an 8" thick concrete slab. There is poor soil below the pool so the 8" thick slab has to be self supporting between rammed aggregate piers. Now, it seems like everything regarding slabs that we have at our...
Okay, I've looked through and only found one topic for this that helped me out a little, but I still have questions. I'm specifying a repair for an existing stone wall foundation that would involve replacing the loose and deteriorated mortar and retuck pointing with new mortar. This is for an...
There's no stone or brick. At first I was expecting to look at a stone and mortar foundation and when I got out there it was just gravel and lime (an assumption - no chemical tests have been done).
Worst case scenario is they replace it, but I was hoping to avoid it if anything safe could be...
I recently inspected an old foundation that has a cement stucco on the interior. There are a couple locations where the stucco has broken off, and the foundation wall has been exposed. At these locations (and I'm assuming along the entire wall) the wall has deteriorated and just brushes off...
I am currently trying to analyze a space frame from a Butler building constructed in the 1970's. My issue is that i don't know what to assume for the yield strength of the steel. If it is 30 ksi, it doesn't work, but if it is 50 ksi it does work. I've tried calling Butler and the person i...
I just received a job that deals with the support of scafolding for a window washer. I've tried looking up information and have reached dead ends on everything so I'm wondering if anyone else has ever had to design the support for the scafolding structure. It's hanging off the masonry wall of...
