文摘

The supplementary energy dissipation using dampers represents an efficient technique for the seismic protection of structural system. Also, the optimal damper location in the building helps in reducing damper cost along with maximum response reduction. In this work, an effort has been made to use the X-plate metallic damper made of steel and aluminium for seismic response control. In the first phase of work, the building has been analysed without and with full dampers under real earthquake ground motion. The response quantities such as maximum displacement, max interstory drift, axial force, shear force and bending moment are compared. The results obtained after the analysis shows that the response quantities are reduced significantly thus establishing the effectiveness of damper to dissipate the input seismic energy. It is important to find out the optimal damper location format in the building to improve its efficiency and reduce total cost of dampers to accomplish the max reduction in the response of the building. Therefore, the second phase of work focuses on the optimal location of the damper in the building. To obtain the optimal damper location, the concept of genetic algorithm is used.
