| Abstract: |
Dynamic condensation has always received little attention from civil engineering community due to the recent huge diffusion of sophisticated Finite Element packages and powered computers. Despite all of this, on hand simple models are attractive for the possibility to manage large systems with very few variables. It follows that prediction of static and dynamic general behaviour under different type of loads speeds up for sensitive analysis. Worst loading cases could be selected and thus applied to a more general F.E. model to display detailed forces inside the structure. This paper shows how to get a condensed dynamic model starting from a F.E. Model through a numerical approach. Three case histories are reported. |
