- Abstract
- A combination of reduction procedures, with fixed-interface component mode synthesis as the central theme, augmented by static condensation and Guyan reduction, is formulated and implemented for a six-story structure with a three-dimensional frame. The validity of procedures and the program is established by comparing results to those obtained from SUPERSAP, a general purpose finite element program model. The agreement is shown to be very good. A twelve-story, three-dimensional building with an L-shape floor plan is also analyzed; results indicate that the combined procedures are advantageous in terms of convergence, the structural characteristics preserved, and the percentage of reduction achieved. Results also confirm the importance of floor flexibility.
