Model conversion technique for structural dynamic systems
Date of Original Version
This technical note introduces a novel model conversion technique for structural dynamic systems that is capable of converting a physically realizable, higher-order model (termed the source model) into a completely different, predefined, physically realizable, lower-order model (termed the target model). Upon the complexion of the conversion, the resulting target model preserves or approximates the dynamic characteristics-the chosen structural frequencies and their mode shapes-of the source model. Mathematically, the procedure to implement the model conversion technique is like a model updating approach, which is fundamentally different from that used in traditional model reduction schemes. A numerical example of converting a five-story two-dimensional frame structure model into a five-story classical/generalized one-dimensional shear-building model is demonstrated. © 2008 ASCE.
