Dear ali_hssn,

I don't think you should have any problem modeling your bridge with SMA isolators. The academic license should suffice for your modeling purpose. The only portion that I think is unavailable in academic license is the Building Modeller module. Good luck.

In addition to Huffte's comment, I wanted to mention that you can also take advantage of the "section curvature" performance criteria. First one should have a good understanding of the model, as where the maximum demand regions exist that causes severe damage in the so-called plastic hinge (PH ...

For defining the fracture/buckling strain, you can simply adjust this parameter for your steel cross section from the Materials tab. And yes, the help system is absolutely right. This parameter should be adjusted with some caution (in the context of performance based design where performance ...

I am not so sure about your question on "if its is better to adopted just the monotonic part with a plastic behaviour", but the answer to your question is dependent on your model and your desirable analysis results. If you have used link elements at beam-column joints to include the smooth curve in ...

For elastic material properties, you can simply define an elastic material (el_mat) in the Materials tab, and then assign it to your beam sections under Sections Tab. For elastic member response, you can also define your beam elements as "elfrm: Elastic frame element" type under the element Classes ...

Thank you really so much for your great input. I had the same expectation when comparing the similar stress-strain behavior of PVC to steel. THANK YOU!

I quickly went through your model. As you thought, your pushover analysis stopped at 1311.19727mm because of failure of your frame. If you just want to get your model running and push your frame up to 2 meter (REALLY HIGH!), just simply go to your material properties tab and change all your steel ...

I have a question on modeling the flexural behavior of concrete filled tubular columns, where the outside tube consists of plastic pipe, like PVC (polyvinyl chloride) material. This system is similar to conventional steel tube filled concrete, where the outside tube serves both as the formwork and ...
