    NFPA 68 Deflagration in (4) four rectangular Rooms that share some common walls.

    Imagine (4) four rectangular rooms, about 10 feet wide x 20 feet long x 10 feet high. Therefore, you have (3) three interior walls that are shared. For simplicity let's say I have designed the walls to be 8", grout-filled, reinforced CMU walls. Would the "shared" wall be (2) two 8" cmu walls...

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    Oh yeah, UcfSE, those tiny loads are 10 psf for collateral/utility loads and 20 psf for roof loads.

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    I really appreciate ALL the input and help guys. Some of it I knew and some suggestions were very helpful. I am a Staad veteran and have only been running RISA for about 3 months now, I like it a lot and a lot of the stuff is the same, just different syntax and nomenclature. As far as this...

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    Node number 76 is the problematic node. Currently the only way I can get the model to solve for All lC is to put a Pin connection at that node. Lunch Time!http://files.engineering.com/getfile.aspx?folder=13650e75-5477-435f-8c00-e0224aae188c&file=delete.r3d

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    Thanks, yeah I've checked all my releases and boundary conditions. I'm applying springs to different nodes as required and it's like chasing a greased pig. I also tried changing member sizes but it didn't work. This is like a Cantilever condition with 2 horizontal and one vertical brace...

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    Thanks UcfSE. I turned P-Delta off for that specific LC and I guess it Solved. But I did get the Warning message 1078 that says the analysis was run without P-Delta. I looked at the deflected shape and sure enough I've got a Node taking off into the ground. It's a node at the end of a monorail...

    Non-Stop Solution Calculation - RISA is in a non-stop cyclical loop of solving my model? What's up?

    RISA 3D is performing a Solution of my model. the dialog box says, "Solution of Combination 1 in Progress... Calculate P-Delta Shears..." RISA is "stuck" in this solution loop and will not stop. What is the problem here? What is the fix? Thanks!
