Finite element model updating based on response surface methodology Slut chat lines free trials

The proposed method was tested on an unsymmetri-cal H-shaped structure.

It was observed that the proposed method gave the updated natural frequen-cies and mode shapes that were of the same order of accuracy as those given by simulated annealing and genetic algorithm.

A multi-objective genetic algorithm (MOGA) was used in optimized analysis to minimize the four objective functions.
