So we were able to get an 8x8 post spaced at roughly 5.5 ft with treated glulam rails to work for the 6000 lb load. And this will be embedded into our 6 foot retaining wall with a 14" stem. Thanks for all the input!
Also, the average car width is 6-6.5, so I am thinking of placing the posts at maybe 5' so they will act almost as a bollard and stop vehicle instead of rail
Thanks for the reply guys. Yes, house will be a single family and there will be a 6 foot drop around a bend so I believe it is necessary there. 2.0 impact factor along with flat use factor, etc. are being used. Calling the town may not be a bad idea as if it is not required maybe we can design...
Hi,
I am designing a guardrail to be atop a 6 ft retaining wall along a residential driveway. The architect is showing 3x8 rail members spaced between posts @ 8' o.c. I have not found any loading in the residential code to use so I have been using the IBC/ASCE 6000 lb load applied at 1'3-2'3...
Thanks for the responses guys!
Yes, so as of now I am using the wind load on a sign and calculating the pull-out tension on the anchors using Roark's cable equations. And the banner will have slits
My thinking was that the curved surface will make it more difficult for air to move around the banner. Similar to a parachute.
Yes, there will be slits that supposedly take 25% of load, but from what I see online 10-15% is more realistic.
Hi,
I have a banner 17'x4' that will span from building to building 16ft above a street. I have seen a couple posts on this, but nothing super clear. How should I go about calculating the wind load on the banner as I don't believe it can be considered a sign as the cupping action of the banner...
