I have an 8-foot deep sanitary manhole that was installed by a contractor that was unfortunately installed out-of-plumb. I am unable to find any standards or tolerances for manhole 'plumbness'. Does anyone know how far out-of-plumb is too much for a manhole? Thanks in advance for replies.
I have a municipal splashpad project - an oval shaped concrete slab, 6-inches thick. The dimensions of the splashpad are: inner oval (with splashpad jets and lights) is 34' x 42'; and the surrounding oval is 60' x 100'. Does anyone know of any guides or resources to help determine jointing...
The 1x6 overlap on the bottom chord refers to the bottom chord splice - there are 1x6's nailed on each side of the 2x6 bottom chord members. The 2x6's are butted end to end at the center of the span.
There should not be much wind loading, as the site is surrounded (three sides) by trees that...
Well, after reading through all the comments and replies, I don't know if I should invest anything into a finished interior or not. Maybe I should not store anything in there over winter, as it sounds like the roof could collapse with moderate snow.
The consensus appears to be that the trusses...
Thanks again for the replies and continued interest. Here's more info:
The location of the shed is central Wisconsin, and snow loading is a concern.
Presently, there's no blocking between the 2x4 purlins.
The peak joint of each truss is secured by a (nailed) 2x6 'gusset plate' on one side only...
Per KootK's questions:
1. I am not a Structural Engineer. I do not see any signs of distress.
2. Agreed.
3. Doubling members is not my preference, due to cost and effort.
4. At the heel joint, where the top chord meets the bottom chord, this joint is also side-by-side (overlap). The 2x10 top...
Thanks for the reply.
The truss members are not in the same plane (no gusset plates) - they are side-by-side (overlapped) and are nailed together. Sample photo attached.http://files.engineering.com/getfile.aspx?folder=4ceb688f-2fb0-4f6d-8f97-0a2271b00697&file=20170324_132422.jpg
I recently purchased a 30' x 40' (unfinished) pole shed, and I would like to add a ceiling and insulate it (along with the perimeter walls). The shed was built (in approx. 1990) with 6x6 posts spaced 8' apart, with wood trusses (spanning the 30' width) attached to the posts. The trusses are...
Thanks for the replies.
There has not been an accident involving a pedestrian yet, so I guess this falls into the 'perceived safety issue' category, but there have been near misses. The real safety issue involves the number of lanes to be crossed. With two lanes of traffic for each direction...
I am looking for suggestions to improve pedestrian safety at an unsignalized intersection. The street to be crossed is a 4-lane urban street, 25 mph speed limit. The street was reconstructed 8 years ago and includes curb extensions/bump-outs, safety islands in the center (with in-street ped...
I'm searching for a simple design for the 'decanting' of sewer cleaning truck (Vactor) solids. We'd like to dump the Vactor solids onto a containment pad (similar to a concrete slab with curb & gutter around three sides), let the solids sit for a bit, while draining the liquid run-off into the...
