Structural modification utilizing beam elementsA method for analyzing the effects of sophisticated beam-type structural modifications to a structure with a known modal database is presented. The modification technique integrates the dual modal space modification method with the transfer matrix method to perform general beam modifications. Consideration is given to two examples: one demonstrates the performance of the modification scheme when a severe structural change is made, while the other demonstrates a change to a complex structure.
