Are you able to tilt the bars to maintain clear cover? Check out CRSI RN-2009-2 Evaluation of the Orientation of 90° and 180° Reinforcing Bar Hooks in Wide Members. It's available for free on the CRSI website bookstore. I've only skimmed through it, but I think it showed very little to no...
I view frost as an "infinite" force. If conditions are right for it to form, it can lift just about anything. I don't know of any calculation that will give frost pressure. I've seen published values of 10 tsf, but I believe they are based on back-calculating the pressure required to lift a...
Check out GRL's website. Most of their software is based on waves propogating in piles. They publish a lot of papers and give a lot of presentations to promote their software.

AWS D1.1 Table 3-1 gives compatible base metal/filler combinations. A36 up to 3/4" thick is a Group I metal that can be welded with E60XX electrodes. A36 over 3/4" thick is a Group II metal which can't be welded with E60XX electrodes. My AWS D1.1 is outdated and your specific project may not be...
Can you just use a mechanical anchorage instead of relying on threads? Something like a foundation "J Bolt" for bolting a sill plate to a concrete foundation wall. There should be manufacturer cut sheets that give capacities.
You can use oversize washer sandwhiched between two nut to create a...
Thanks for all the responses. I looked into RISA 2D for the moving load analysis, but unfortunately RISA has moved to a yearly subscription license. I don't think I would use it enough to justify a yearly expense. The trend of moving toward yearly subscriptions for program licenses is becoming...
I'm working on a work trestle for an upcoming bridge construction project. The contractor would like to back trucks with bridge beams onto the trestle for unloading. The truck/trailer/load will be +/- 140 kips on 6 axles. The trestle beams are simply supported spans. I'm trying to do this by...
I'm not sure why it was discontinued. The professor that created it moved to another school. Maybe the rights to the program belong to his previous school?
Fachwerk seems to be the other free program. I started playing around with it but didn't get too far...
I am designing a tie beam between two drilled shafts. My tie beam is 39" tall x 42" wide. I have a question about AASHTO LRFD 7 Temperature and Shrinkage steel requirements. I calculate a required area of steel = 0.22 in^2/ft. AASHTO calls this "area of reinforcement in each direction and each...

Thanks TME. I found some examples in the C\Program Files\Cast\Examples folder. I copied the truss from the deep beam example. I'm still working out the strut/tie types and node regions.
I was able to access the University of Illinois CAST page using the Wayback Machine. It has some FAQ and other helpful info

Thanks TME. I'm still struggling with this. I modified my model to include edge nodes with supports, but I still can't get the model to run. Right now I'm at this:
Is this what you mean? If not, could you provide a quick sketch?
