| Abstract: |
This study presents a new integrated method for evaluating structures with viscous and tuned mass dampers (TMD) through the Center of Mass (CMO) optimization algorithm. The considered structure is a special steel moment which it is designed in three scenarios as bare frame, viscous damper equipped and TMD equipped structures. To optimally design the structure, CMO metaheuristic algorithm is used for minimizing weight and also keeps strength, dimension and damage indexes limited. For this purposes an inter-connected approach is used by linking OpenSees and MATLAB softwares. The CMO optimization algorithm is conducted in MATLAB, while the nonlinear seismic analysis is implemented in OpenSees. The seismic evaluation included nonlinear time history analysis and Incremental Dynamic Analysis (IDA) which is used for providing seismic fragility curves in various performance level states. Based on results, the optimized structures exhibited damage indices within the repairable limit state per FEMA guidelines. And viscous damper systems reduced the total damage index by 5% (5- story) and 4% (10-story) compared to TMD-equipped frames. IDA curves confirmed a better performance over viscous dampers in performances, demonstrating significantly lower seismic fragility relative to both TMDequipped and bare frames.
