SINGLE SPRING CONSTANT IN STAAD/PRO OR RISA-3D PLATE ELEMENT MODEL FOR RAFT FOUNDATIONS:ДЄ)This not a problem. Posted: Fri 10:18 am Post subject: SINGLE SPRING CONSTANT IN STAAD/PRO OR RISA-3D PLATE EL. Can seniors please share their experience? Is the assignment of a unique 'ks' value justified? But, in actual scenario the settlements are larger under the center point and lesser towards the ends. Here the 'ks' is based on tributary area. Using a uniform 'ks' value under a rectangularly loaded footing will produce constant settlement at each point. Now, I have noticed that, consultants tend to use the same 'ks' value ( where ks is the modulus of subgrade reaction) under all points in combined footings or rafts. To simulate elastic foundation we use springs. We know that the base contact pressure contributes to the settlement in footings and that there is no dependence of modulus of subgrade reaction on base contact pressure.

Then use the copy rotate feature to copy that slice around to form the whole dome.ДЄlso, if you guys have the current version of the program, just e-mail the support group ( some basic drawings and we could probably provide more detailed guidance.Warning: Make sure you scan the downloaded attachment with updated antivirus tools before opening them. Then spend some time modeling the plate elements or members that will fully model that slice. Once you've got a 2D slice of the arc modeled in RISA, then it's just a matter of using the center point of the arch with the copy-rotate feature to copy it through one slice of the pie. one of the advantages of being a spreadsheet based program.Дў) Draw the arch in AutoCAD and use the DXF function to bring over the basic coordinates of the arc. Then copy and paste the coordinates from Excel's spreadsheets into RISA's spreadsheet. If you cannot get RISA's arc commands (circular or parabolic) to adequately model a cross section of your dome then bring in the basic geometry another way.ДЎ) Set up an Excel spreadsheet with equations which define the 2D geometry of the arch.

Makes you wonder how Walther Bauersfeld and Buckminster Fuller ever did their domes, before computers, or when computers were as large as the domes themselves and could do less calculatin than your cell phone can today. When you overcome one idiosyncracy, that brings three more into play.

These programs can do amazing things, almost anything, problem is, mere mortals can't figure out how to make them do it.

It makes me wonder how anything ever got built before the advent of computers, and the complexities of them and the software they spawned became an end in themselves, not a simple means to an end. And, the damn program doesn't tell us that detail it analyzed can't practically be fabricated or installed, it just gives us a high von Mises stress that we don't understand either. We are all forced to get mired in the minutia of these programs, to the point that we forget what the original problem was, but we know it to 12 decimal places. I suspect that you and I would have one hell of a time even trying to deal with the program complexities, I know I do, given the way you and I approach design problems during the prelim. But, you didn't offer any software that will do our elementary and preliminary thinking for us. There you go again, you provided a clean, simple, basic solution for the question asked. 'I don't know anything about RISA 3D, but.' Me too, but.

You might want to hit him up, again, for a little more help. RISA (JoshPlum, am I correct?) 12:45, on 23MAY11.
