I am trying to model 2-D steel frame 6 storeys and 3 bays. In the middle bay I am using X-bracing made of steel with SMA in the end zones. I want to show the recentering capability of the SMA bracings by comparing this with traditional steel bracing. So, how should I model steel bracing with SMA in the end zones ? I am carrying out non-linear time history analysis for different earthquake ground motions.

hitesh4894, hi.

I carried out a search (in this Forum and on the web in general) on the word "alloy", and readily found a number of suggestions/proposals on how to proceed with the modelling you mention, the most recurrent of which involved the introduction of adequately calibrated springs at the ends of the frame elements.

Best,
