Optimal allocation of non-linear viscous dampers for building structures
By incorporating passive energy dissipation methods, structural integrity can be maintained under cyclic loads caused by seismic activity. This study aimed to evaluate the performance of viscous dampers by employing finite element method (FEM) simulations via SAP2000 software on seven-story reinforced concrete (RC) frame structures. First, dampers are positioned at the edge of each level to analyze the structure’s response to four seismic datasets. The utilization of dampers significantly mitigates damage characteristics such as displacement and drift. Nevertheless, logistical constraints render it impractical to install dampers on every floor. Consequently, a positional optimization employing evolutionary algorithms is conducted to identify the most favorable damper locations, considering configurations with four and eight dampers. By minimizing a predefined objective function, the optimization procedure identifies optimal positions. Subsequently, the results for the optimal locations are compared with those of the no damper case and full damper case.
