gbam: Thank you for all your input, again, I truly appreciate your time. I will surely check out the site.
francesca: Yeah, I didn't explain things very well, and it's hard to grasp the site without pictures/plans. Essentially, I have two rectangular lots side-by-side. Each lot has a single...
(A) brandonbw: I have seen the V-ditch and there is a lot of dirt in it. There are very little cracks (that I can see), but the finish is pretty rough. My final plans will require soil erosion protection of the adjacent slope (the V-ditch is below our two lots by about 13 ft). The V-ditch is at...
In doing some preliminary/final calculations to check the capacity of an existing concrete V-ditch I wanted to summarize, and ask about, the design steps I use. There are two residential sites, one 24000 sf and another 16000 sf. The larger site will be connected via a 6" or 8" pipe (85' long)...
On page 5 of the 2006 Simpson Anchor catalog, there are notes for the allowable shear and tension capacity for rebar that they use. You should be able to find the catalop online.
francesca:
Yes. Except the dispersion wall is actually a wall (e.g., 6" block) in a concrete "detention basin" about 15" deep. There are three levels of protection: (1) you have area drains in the concrete basin that drain under the wall down slope and feed into a perforated pipe (level...
Has anyone used anything other than dispersion walls or rip-rap to convert concentrated flow to sheet flow? I am trying to drain a sloping (5-10%) residential property to an existing, natural ravine at the back of the lot. We could also use a sump pump to get the water up the slope to the...
Does anyone use anything other than dispersion walls or rip-rap to convert concetrated flow to sheet flow? The owner of this project is also thinking about using a sump pump. It seems there are a lot of disadvantages with this option.
Any feedback would be greatly appreciated.
I would say get an MBA and go into the "business" field of some kind. The work is less, the liability is 0, and if you work your way to the top there are million dollar pay offs!
I have been involved in a couple of custom homes where we resisted soil pressure with the diaphragms. However diaphragms are only part of the issue here. Once the load is in the diaphragm where does it go? The next big step for us was designing the lateral system for both seismic (I'm in CA)...
When I design beams for custom homes, I look at deflection but I also consider vibration due to walking. A typical criteria I use to design steel beams is that the depth should be at least L/20. This, I believe, comes from one of AISCs steel tips booklets. For deflection, I will try to keep...

Be carefull about "fixing" the edges of the glass. What about thermal expansion? I was involved in a custom home where the owner and contractor went to great lengths to ensure that the glass windows at the back of the house facing the ocean would not crack due to thermal expansion...

Do you have a reference for the 10 ksi value? Like I noted, I have done some glass railing calc's., but I would like to have a more accurate value. It seems more and more owners are looking for glass railings for their decks, and sometimes they ask me for calc's. Thanks
What I typically do is design a "bent beam" to support the hip(s) and if present the ridge. Typically there are two hips and a ridge meeting at a point. The "bent beam" can be thought of as two rafters--that is, at the point where the two hips meet the ridge, there are also two rafters that...
