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...
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...
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...
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...
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...
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...
I have a concrete frame with biaxial bending in the beams and columns. I'm wondering if anybody knows of any GOOD literature or examples on this topic. I've been trying to go through an example by Edward Nawy but I've been getting lost in the process. Basically, my moments are high relative...
I have a situation where the steel fabricator is using 1/4" diameter steel cables for the infill area of a guardrail for a stair. I have to check the infill for a load of 200 lbs on 1 sq. ft. of area so that people don't fall out the side of the stairs. I'm wondering the best way to check this...
