Can anyone provide a source for detailed worked examples of seismic frame design besides the SEAOC Design manual publications? I am specifically interested in eccentric and concentric steel braced frames at the moment and not sure if I am interpreting some of the detail provisions correctly.
Thanks for the responses so far. MiketheEngineer - LOL - not long anymore.
The welding will be wet at depths of 5' to 25'. The diver is saying 1/8" is the maximum size he can make. We were thinking 3/16 to 1/4 in a single pass. Never heard that multiple pass welds were out of the question...
Can anyone tell me the maximum size of a single pass fillet weld performed under water? Also how much performance loss to expect from both single and multi-pass welds underwater?
Thanks
What is the maximum size of a single pass fillet weld made under water (25' or so depth)? Also, what is the maximim size of a multi-pass underwater weld? Just had a contractor telling me the maximum underwater weld size is 1/8". I've never heard this before, but it is not my area of expertise...
The page 3 method is legitimate if you provide a shear transfer member along the wall across the head of the opening and continue iotacross the wall on either side. Blocking between studs and tension straps are one way to do this. The sheathing above and below the blocking line must be nailed...
Bill Carr was/is one of the sharpest engineers I've ever met. Amazing memory for obscure structural info and where to find articles/information on just about anything. Leonard was accomplished and modest - a very good, gentle teacher and probably the nicest guy I ever worked for. Learned a...
Sure does - I did strip centers, apartment developments, industrial new and modifications, commercial buildings, 3 to 5 story steel frame office buildings, new design and renovation/redevelopemnt projects. When I left I couldn't drive more than a couple miles without passing by or within a...
MiketheEngineer:
People have been saying the federal courts are "all wet" for years. Sounds like the plumber's defence ought to be "what's changed?".
My case is a 2" line in an office-warehouse that reportedly flooded the building to a depth of around 3" when the first guy in discovered it...
Thanks Mike,
Any idea if there is a specific code section (mechanical or plumbing) that requires anchorage to resist the hydrostatic pressure? From what I can see the plumber did anchor the end of the pipe that slipped, just did not understand that wall plate-to-stud nailing is not really...
Thanks for the replies gentlemen. The belling of the coupler does look like it allows for the amount of visible misalignment. I have checked the plumbing code and see no absolute requirement for clamping pipe runs except for vertical support and seismic bracing. This pipe extends upward about...
I may be google challenged, but I have not been able to find any manufacturer specifications for allowable misalignment and I do not know the make or model of this particular coupler. The installation is not in St. Louis.
I do not know exactly what the fitting is - it appears to be threaded onto a "T" above the shut-off valve and a compression fitting to the distribution pipe. Hopefully the attached photo...
I am looking at a water delivery pipe failure and need a little help. The pipe is a 2" I.D. steel/iron line from the main and the failure occurred at a coupler that was used above a new shutoff valve. The coupler is a friction fit (non-threaded) where it attaches to the distribution line that...
I have been looking for information regarding what is an acceptable amount of misalignment of pipes. Specifically I am looking at a repair where an apparemntly threadless splice fitting is used above a new valve and the centerline of the connected 2" steel pipe that extends from the fitting is...
