    RISA-3D vs Visual Analysis (and others)

    I'm reviewing VA right now and it seems pretty decent the way it's laid out. I think I'd go with the building suite. I have a separate steel connections program but it's outdated. If I renewed it would probably be subscription based as well. I have the WoodWorks suite (Sizer, Connections...

    RISA-3D vs Visual Analysis (and others)

    Just checked RISA's prices and how their products are sold. Yeah, annual subscription for all now. So if one got RISA-3D, RISAFloor, RISAFoundation, RISASecton and RISAConnection it would cost me $5,275/yr. I don't think so. It looks like the VA Building suite, which includes most of the...

    RISA-3D vs Visual Analysis (and others)

    So if I lapsed I'd probably need to purchase the current versions and then be on a subscription? I haven't check what their purchase options are now. Sorry to hear about your, Bruce and Rodger's departure. You guys were very helpful with support over the years.

    RISA-3D vs Visual Analysis (and others)

    I've used RISA-3D, RISAFloor, RISAFoundation and RISASecton from some of their earliest versions but, several years ago I stopped maintenance as it got just too expensive for a one person office with limited income (semi-retired). But occasionally I get projects that are just made easier by...

    plate/member interaction

    I think I found the problem. It appears that rigid links used to pass the floor joists over the supporting beams was the problem. One end was pinned the other free. When I pinned both ends the shear force Vz in the joists disappeared. The floor is tied into the walls/arches so stability...

    plate/member interaction

    Josh, Attached is the floor photo. Guess you can't upload more than one file with a post.http://files.engineering.com/getfile.aspx?folder=19e7e291-f43c-4376-8964-927c7972ec9c&file=Barn_Floor.JPG

    plate/member interaction

    Hello Josh, Yes, that's true. One shouldn't be using a density of 31 lbs/ft^3 for the plywood material either. Anyway, removing the plane stress option and refining the mesh didn't make any difference. The center bay still has members that "lock up" Vz forces. The mesh is about 6"x6"...

    plate/member interaction

    I've modeled plates supported by members a number of times but just recently noticed an odd effect in the members being support. It might just be the scale of the model, but anyway I'm just wondering if anyone has seen this as well. The problem: I'm modeling an old barn with a wood floor...

    Table arrays

    Alex, Thanks. I ran into some indexing problems but now think I have a handle on it. It's a bit more complicated than yours but it does what I want it to do. Again, what I’d like to do is enter either force loads or displacements explicitly at nodal points. What I was able to do was set up...

    Table arrays

    Alex, Thanks. I’ve been going thru the sections on arrays and tables and haven’t quite been able to figure it out totally. Asked the question of the ANSYS folks and got a similar reply and an example. Here are are few lines from an input file: !* Create Table *DIM,ddy,TABLE,10,1,1,X, , !*...

    Table arrays

    Is it possible to define a table array such that it may be used for displacement or force loading at element nodes? I've tried to define a table using 1 column and n-rows with the row indices being the node numbers. The column holds displacement or force loads. What happens, when using the...
