Özet

Viscous dampers (VDs) are remarkably effective passive energy dissipation devices successfully implemented in building structures to reduce seismic demands during earthquake excitations. Viscous dampers can be utilized to enhance the resilience of structures against earthquake excitations. Besides that, they can be used for seismic rehabilitation of existing structures. Viscous dampers influence the dynamic response of the building structures that they are attached to; therefore, their allocation is vital. Furthermore, the optimum design of viscous dampers is another critical concept since they are expensive devices; thus, their optimum distribution results in a more economical method. This study suggests a methodology to rehabilitate existing building structures with soft story irregularities via optimum viscous damper distribution using the Particle Swarm Optimization (PSO) algorithm. Soft story irregularity causes significantly large peak inter-story drift ratios (IDR) and abrupt changes in peak inter-story drift ratios between adjacent stories. The primary objective of this study is to limit the peak inter-story drift ratios to an allowable limit. In the scope of this study, the suggested procedure was tested on shear buildings with soft story irregularity under different earthquake ground motions. The results of this study show that it is possible to keep peak inter-story drift ratios at an allowable limit with an optimum viscous damper distribution for shear buildings with soft story irregularity. Moreover, this study shows that the Particle Swarm Optimization algorithm can be successfully implemented on optimum viscous damper design problems in building structures. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
