Hello, Can you post your tcl files? I also want to see the difference. Thank you very much. [quote="Xiang Wang"]Hi, silvia, I've just conducted a nonlinear fiber section analysis, in order to test for the Arc-Length Integrator. Compared with the results by Displacement Integrator, two curv...

Hello,

Is Arc-Length integrator a StaticIntegrator? Does this mean that it can only be used in static analysis? When I used it in transit anaysis, I got "WARNING analysis Transient dt tFinal - no Integrator specified,
Newmark(.5,.25) default will be used".

Thank you all.

Hello, I want to try the NewCommand and NewIntegrator using API but met some errs. I first open the windowsDLLs.sln and add them exist projects. Is that right? Also I build/rebiuld the miniPackageCPP but fails. Thank you all for help me. 1>c:\users\newton-b\desktop\opensees2.2.1\opensees2.2.1\packag...

Hello, can you tell me how is this curvature defined in a zeroLength element?
set Ky [expr $epsy/(0.7*$d)]

EXAMPLE 2 -- Moment-Curvature Analysis of a RC Section
epsy is steel yield strain, d is colDepth-$cover.

then why the curvature is the epsy/(0.7*$d),

Thank you.

Hello, I have a question about zeroLength element. I know that the curvature is the inverse radius of a beam section. But what the curvature is for zeroLength element. If I define the moment-curvature property of a zeroLength element, is the curvature here the relative rotation between two nodes of ...
