Hi
Hoa can I recorde damage index of Fatigue material?
Dose this material work only with fiber section?

Hi
I want to model a frame with a leaning column for P Delta effect. Which type has
less converge problem, 1- use equal dof 2- use rigid link or 3- use a very stiff elastic truss element?
if I use equal DOF, Can I use RCM numberer?


Thanks

Hi
I want to model beams with pinned connection. Which type has less converge problem in transeint analysis, only constraint translation DOFs or constraint translations DOFs and use a rotational spring with very low stifness?

Thanks

you can play with pinchX and pinchY to not have pinching behavior (compare pinchX=0.2 pinchY=0.8 to pinchX=0.8 pinchY=0.2). the curved looks like that of steel02, except for the lack of smoothness, but you can have a trilinear curve.

Hi

Where I can find about isotropic strain hardening model of Steel 01 and 02?

Thanks

Hi
I examine the hysteretic material but this material shows pinching behavior.
How can I define bilinear steel material with different yield stress in tension and compression without pinching behavior?
thanks

Hi
I want to model buckling restrained braces (BRBs).

Dear friends
How I can model concentric braced frames and buckling restrained braced frames?

Hello
Does this version support nonlinear beam column element with pined end?
