文摘
- •
A complete framework for seismic design optimization of composite buildings is presented.
- •
Buildings have: steel HEB-columns encased in concrete; steel IPE-beams; steel L-bracings.
- •
Member capacities are checked according to Eurocodes 3 and 4.
- •
Seismic system performance is checked using nonlinear pushover and eigenvalue analysis results.
- •
Cost-effective structural designs are identified using a discrete evolutionary optimization algorithm.
