    SAP2000 compatibility with Revit Structure

    As I understand it, Revit interfaces with Autodesk's ROBOT which is the SAP of Autodesk. I'd say ditch SAP for ROBOT since compatibility is guaranteed and Autodesk have been pretty aggressive on the features too so should be competitive vs SAP. But I don't have much engineering experience so...

    Abaqus and Visual Studio Debugger

    Also I'm impressed you got visual studio working with Abaqus, I barely got it set up myself and then coding the blimin FORTRAN77 subroutines is such a dog.

    Abaqus and Visual Studio Debugger

    Sorry to be of no help but I had a similarish issue when trying to invoke Abaqus from PyDev in eclipse. What was happening there, was that abaqus was being invoked using different "environment flags" or something and this made it crash unexpectedly with no error message. I think in your case...

    Cutting up already existing assemblies into parts

    So what I've been doing is: Draw the old part/assembly Import the old part into a new part and call it OldPartCut Use the split option to split up the solid into several parts (including offcuts) Export those to new parts (this part is a manual operation) Then use the new parts as I please...

    Cutting up already existing assemblies into parts

    I'm about to make a steel frame to run some experiments on and I'm trying to figure out if there is a way to solve my problem: I have the drawings for an assembly (it is a metal frame, about 250in tall and about 400in wide, made of hot rolled sections). However that frame is no longer in use...

    Subroutines in ABAQUS

    http://imechanica.org/files/Writing%20User%20Subroutines%20with%20ABAQUS.pdf Might be of use?

    ABAQUS - same model, different steps

    Thank you for that portliner. I've done that before with the activate, deactivate. What I might do is use a script to activate all the relevant ones at a time once the file is large enough.

    Problems with units with regarding nanoindentation.

    I find it easiest to stick to SI units no matter how stupid the inputs seem. So input it all in Newtons, meters and seconds, even though your micro meters would have a x10^-6. Having said that I'm now using inches, pounds-force and seconds and it is a nightmare.

    modeling of a Euler Bernoulli beam with solid elements

    What would be the purpose, can you let us know? I'd imagine it would be a nightmare to specify plane sections remain throughout the beam and whatever other assumptions there are.

    ABAQUS - User Subroutines on Windows 7 and on a cluster computer

    Hello, I'd like to know if I'm able to take advantage of user subroutines on the following two platforms: -Windows 7 - I understand you need a FORTRAN compilier, but must it be Intel's pricy one? There are others out there, but they seem to require you to have pseudo-linux environment and I'm...

    ABAQUS - same model, different steps

    I've got a bit of an organizational question: -I have the same model that I need to subject to different time histories. -So one model and I need to do the following --Static Load (pushes it into non-linearity) --Pushover (pushes it into non-linearity) --Cyclic time history loading (ends up...

    Moment-Rotation Curves

    I don't think Abaqus will do it automatically. You need to get a free body cut at where you want the moment and sum the forces on those nodes to get a moment. For rotation, kind of depends on what you define your "plastic hinge zone" as. If that is how you're idealizing it. Rotation is then...

    Connection load transfer

    You'll get some moment transferred, it depends on what kind of connection. As an example, if you have a cleat that is on the side of an I beam, that has three bolts, all the rotation is transferred into the I beam. However the I beam can't handle torsion well so you'll idealize it as a pin...

    Yield line capacity vs. interaction with other stresses

    This isn't a response to your question, but don't forget the eccentric weak axis moment on the column due to the brace.

    Common method to apply loads on ABAQUS

    I've done coupling to apply what would have been idealized as a point load before. Also it is possible to define an area that the "concentrated" load should be applied over and apply there. If you can't really idealize your load to a coupling or an area load then you'd want to model the extra...

    using symmetry in CORRUGATED Plate

    That would be true as long as there are no forces in the lateral direction. I've tested a simple beam in Abaqus and it does have some built-in buckling algorithm. So if you're loading it and expecting lateral buckling then symmetry is not appropriate. Symmetry is OK if the two parts are exactly...

    Bolts in ABAQUS

    Depending on level of detail wanted, I've tended to use beam elements with a coupling constraint on the bolt hole at the surface. These worked fine since my bolts were pre-tensioned. However, I have seen full bolts being used and everything was lumped together (head, washer and nut) into one...
