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.
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...
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...
I am discussing repair of the surface of exterior slabs on grade with a property owner. The slabs were exposed to 2 or 3 unknown chemicals that have discolored and mildly etched the surface. The owner is adamant that no coatings or cementitious overlays be used for fear of poor long term...
We are repairing a steel structure originally constructed using 50 ksi cor-ten structural steel. Corrosion in various members differs from nil to completely missing webs and/or lower flanges in places. Framing members will be replaced selectively, depending on the extent of corrosion.
We have...
Any one out there have experience with ASCE 31-03. I am repairing a steel frame parking structure (substantial alteration due to scope) which has a braced frame lateral system that does not meet current code, but is close. The building department allows evaluation using ASCE 31-03 as an...
