How do I do a pushover analysis of a jacket structure?

Pushover analysis of a jacket structure

Sesam includes the program Usfos that is recognized by offshore structural engineers as a leading non-linear software tool, not only for pushover analysis, but also for ultimate strength under loads resulting from explosions, fire, ship collision, dropped objects and earthquakes. The plastic hinge approach of Usfos reduces the normally time consuming effort of a non-linear analysis to a time efficient process demanding less computing resources.
