    Structural Analysis in the Cloud - CloudCalc.com

    I certainly expect them to start charging at some point, nothing wrong with that. It is an interesting experiment.

    Salary increase with MEng?

    blc219, are you now more valuable to the company? As an owner, I can tell you your boss is more interested in your value to the company than he/she is in what degree you have. When you go in to talk about it, frame the discussion in those terms (your added value) and your boss should listen to...

    STAAD and RISA 3D input file

    The RISA input file IS a text file and can be edited in any text editor. Here is a snippet from a Version 8 file: [.HR_STEEL_MATERIAL] <5> "A36 Gr.36 " 29000.000000 11154.000000 0.300000 0.650000 0.490000 36.000000 -1; "A572 Gr.50 " 29000.000000...

    Actually what you want is the ANSI/TIA 222 G. You can get it at www.tiaonline.org/standards. Good luck!

    Limitations of Software Packages

    Certainly I'm not suggesting he write his own solver or even that he switch software. What asixth should do is contact his current vendor and press them to improve their solvers. Again, this is the long term solution. Highly robust solvers can make modeling much easier.

    Limitations of Software Packages

    This is a software issue, not a RAM issue. Good blocked solvers and sparse solvers can solve most any size model with limited RAM. BTW, Etabs has good solvers. Adding RAM, switching to Vista are viable band-aid solutions to get you through this particular model (hopefully) but improving the...

    Rod X-Bracing In RISA 3D

    So it was an input error... Yes, these programs solve the problem you tell them to solve. It's the engineer's job to make sure the correct problem is being solved.

    FE software, can it be that cheap...??

    This is a pirate site. Do you really think software vendors want to sell old versions at greatly reduced prices? It's not like last year's cars sitting on a dealer's lot.

    How to work 2D problem in risa 3D

    Staed79, Assuming you're working in the XY plane, use the "ALL" boundary condition to set the BC for Z, X Rotation and Y Rotation to "Fixed". You can do this by entering ALL for the joint label in the "Joint Boundary Conditions" spreadsheet. This will lock all your joints from out of plane...

    Pinecar Derby Lubrication

    The rules do vary from pack to pack, some require graphite, others allow anything so long as it doesn't foul the track. Graphite has always been the standard for pinecars, I'm just wondering if something else might work better!

    Pinecar Derby Lubrication

    And on a not so serious note: What is the best lubrication for pinecar derby cars? These involve a plastic wheel spinning on a metal (steel I assume) screw or nail. Everyone recommends dry graphite, but I think there may be something better, such as: Silicone spray? Elmer's Slide-All (Teflon...

    Isn't the AISC's CIS/2 project supposed to integrate all these products?
