To use the Wen Plasticity property you'd have to understand the implications/assumptions of their parametric definition, which I admit I never looked into.
If you're not looking to model any hysteretic behaviour, the simplest way is just to use the multi-linear elastic link. You can basically...
Hi all,
I have been using SAP2000's section designer to generate moment-curvature for some columns, but keep running into an error: "Error Occured in Form MomentCurveGridForm. Please correct data and try again." The strange thing is that it only happens with some sections, and seems to be...
I assume you're no longer stuck on this issue, but I just had one idea (since my main line of work involves lots of time histories - and lots of convergence errors!)
If you stop your analysis and create a video of the structure up to that point, you may see what's going astray with the model...
If I understand your question correctly, you want to apply a time history to specific joints, and not as a general global motion (as you would for an earthquake time history)?
Then yes, you can: (this example considers imposed displacements)
1. define a load case (ex. DISPLACEMENT)
2. assign...
You should be able to model a TMD device with the various nonlinear link elements available in the program, unless you require something very specific.
You can get nonlinear stiffness curves (for a capacity cut-off, hsyteretic behaviour, etc.), damping, and you can also assignment mass and MOI...
I agree with WillisV - the t3 and t2 properties are there so that the elements can be seen as shapes (and not lines) in a 3-D extruded view of the model.
Just so no one has to feel wary about using a general section and avoid it! (you can also convince yourself by checking with a 1-DOF model)
