SAIL3, See attachment below. The design wind speed is 120 MPH, Category B Exposure. After some thought I am thinking about using a combination of the Open gable and Open mono slope coefficients. Just trying to make sure proper judgment is used. I am sure this is not the first time an open...
I am currently working on the design of an open arch canopy system, and there is not much guidance for this type of roof system. Does anyone have any references or know if ASCE has any additional design examples available? I am having a hard time finding any information.
In order to work...
All,
Thanks for the great input, and thanks Ingenuity for the information on the triangular mesh. I believe this may be what was used and I will look at the resources you have provided to determine what grade the strands were in that era. The only thing that still has me thinking is it appears...
Hello,
I am currently evaluating an existing concrete floor slab that I am told was constructed in the 1950's. I found an area of exposed reinforcement and it appears to be wire strand that could be a pre-stressed or post tensioning cable. No signs of any "pockets" and the slabs are supported...
Little Inch,
The extra load which is vertical load (hence frictional load) is resulting in a non "Standard" structural support frame as shown in the image of my earlier post.
I appreciate all of the input and keep it coming.
I guess it comes down to a couple of options:
1. Either design...
No friction loads at the anchor support. Just the slide locations. Delagina, the thing I am trying to sort out is the difference in the net weight of the pipe Vs. the vertical load from the operational case is about 9 kips Vs. 25 kips on the slide supports on either side of the bridge. So you...
Sorry if I wasnt clear on the original post. I have attached a sketch of the system.
The support on the left is an Anchor loacation. The two supports on the sides of the bridges are slides. After putting some thought into it, the expansion loads are the final loads during operation, and the...
Hello,
I am currently working on a design that involves a pipe bridge and pipe supports, and there is some disagreement on how the friction loads are determined for the supports. This is not a typical senario, as the pipe loop that goes over the bridge serves as a verticle expansion loop. The...
