Thank You!

Dear STKO Team

I am dealing with pushover, cyclic and nonlinear time history (NLTH) analysis of prestressed pile supported slab viaduct structure.
I use N, mm units in my STKO model.

I also model the structure using SAP2000.

I tried to adopt the STKO e-learning course to perform my STKO ...

Thank you, now it works.

Then, I try to modify my model. I model the slab using face instead of frame element (edge). Then I assign the self-weigth & mass of the slab using forceFace and massFace. But now the model error. I try to follow the 3rd Getting Started in OpenSees with STKO webinar. I ...

Dear Fransesca

I have update my OpenSees slover. It works now, The modal analysis result appeared. thank you!

I have checked out the thread & last webinar, I think the local axis does not problem. But, I found that there is a triple pile element in the same location. I fixed it and the internal ...

Dear Fransesca,

Big thanks for your explanation. Your explanations help me a lot. I am trying to understand. :)

I try to run the modal analysis. The analysis works, but the result did not appear from the post-processing as the thread you shared to me. I have checked the modesOfVibration in the ...

Dear Francesca

First, thank you for your detailed explanation, it helps me a lot. I tried to modify my model following your suggestions.

I forget to input the Ec :lol:
I modify the self-weight and mass of the structural element using EdgeForce and EdgeMass, respectively, instead of using ...

Dear Horace Horsecollar

Thank you for the response and reply,

I have meshed the model. But the gravity and dynamic still not working. Is the meshing wrong?
I see in the ASDEA example (NLTH of bridge), the mass is "black" too. Where should be the mass assigned?

Best regards

Dear STKO Team

I am dealing with nonlinear time history analysis of a pile supported slab. The pile is hollow concrete prestressed pile.

I try to set the dynamic analysis following the ASDEA webinar about NLTH analysis of bridge. But my analysis still don't work.
I think there are still some ...

ooh i see, thank you

Thank you, STKO Team!!

I tried to use fiber section with Steel01 material and i get this problem, what does it mean? And where is the problem?
