multi-objective shape optimization of steel shear panel dampers

Shear panel dampers (spds) have stable energy dissipation capacity as well as low material and fabrication cost (deng et al., 2015). along with the recent evolutions in computer technology and numerical analysis methods, the implementation of optimization algorithms in a wide range of engineering mechanics problems is substantially increased.hedayat (2015) employed optimization algorithms and finite element updating methods to improve the cyclic behavior of slit dampers. liu and shimoda (2013) implemented shape response surface method (rsm) to improve plastic strain distribution of spds under cyclic loading. the edges of samples were assumed to be parabolic and the optimal parameters for the parabola were obtained using regression analysis. the results showed that edge shape optimization can beconsidered an effective approach to improve the cyclic performance of spds.
