- Abstract
- As computer power is increased, refined finite element models are employed for structural analysis. However,it is difficult and expensive to use refined models in the design st age. The refined models especially cause problems in the preliminary design where the design is frequently changed. Therefore, simplified models arc needed. The simplification process is regarded as an empirical technique. Simplified and equivalent finite element model of a structure has been studied and used in the preliminary design, A general approach to establish the simplified and equivalent model is presented The generated simple model has satisfactory correlation with the corresponding refined fmitc element model. An optimization method, the Goal Programming algorithm is used to make the simple model. The simplified model is used for the design change and the changed design is recovered onto the original design. The presented method was verified with three examples.
