Klitor, I'm just getting into using Allplan now and it looks pretty solid. What gave you the impression they are dying? I'm not familiar with the development history of the software, just started with the 2018 version of it.
You can also use the interaction expression from RD.7 that raises the terms to the 5/3 power and limits it to 1.0. There is a graph in the commentary that compares the two.
You don't have to worry about interaction if you can ensure all the tension goes into anchor rod and all the shear goes...
Are you taking all of the of the losses? I usually assume that half of the losses have occurred in the yard before erection. I feel this is safe because most of the losses over the life of the beam occur in the first weeks.
Also, I assume when you say you are using Hooke's law that you are...
When designing anchorage to concrete in bridge design, I usually use ACI Appendix D which has provisions for seismic in D.3.3. If you are using rebar to anchor in, then you would use AASHTO 5.11 and there are no seismic provisions there.
Is it a #4 bar going 20 inches? a #5 going 25 inches? Both of these seem reasonable especially if you have a class 3 splice.
Also, epoxy coating increases development length.
Close to an edge and it gets longer.
It's part of a dowel system but this approach can be applied to any anchor close to one free edge with shear applied at an angle not perpendicular or parallel to the edge. I'm attaching a sketch right now.
Two more questions :
Since both loads are occuring at the same time, is interaction...
I have a dowel system that will be connecting two slabs together and it will be seeing vertical loads due to gravity and lateral loads due to earthquakes. Do I simply calculate the breakout capacity perpendicular to the free edge and compare that against my gravity loads then double it (to get...
Hello,
I am designing a small bridge in New Hampshire that is 28 ft long and 16 ft wide made of (4) 14" deep x 4' wide solid slab beams. My company provides engineering and CAD services to fabricators in the north east. We have not done a design like this in NH before but have done many like...
