Metaheuristic Optimization

Metaheuristic optimization methods (harmony search, genetic algorithms, ant colony optimization, particle swarm optimization, simulated annealing, etc.) are concerned with optimization of highly nonlinear problems that may involve both discrete and continuous design variables.

Areas of interest:

Metaheuristic optimization methods for (linear and nonlinear) steel frame optimization
Design driven metaheuristic optimization methods
Metaheuristic optimization methods for connection topology optimization
Optimization for robustness: progressive collapse prevention

3D steel building frame models used in optimization studies

Steel frame elevations with member groups under wind load

Steel moment frames with optimized connection topology
