Rational design of lightweight earthquake resistant buildings with friction dampers using the particle swarm optimization

Abstract

EN: According to the principles of sustainable development and circular economy, an important task of Civil Engineering is the design and employment of lightweight economic structures characterized by low resources consumption throughout the all stages of their life cycle. The resistance of such structures to seismic loads is provided by special devices: seismic insulation, inertial vibration dampers and friction dampers. In recent years, dry friction dampers are widely used because of the simplicity and reliability of the design, low costs, easy installation and maintenance, as well as high dissipative properties. Determining the location of friction dampers inside a building is a complex task that requires a comprehensive analysis of the dynamic properties of the structure and, as a rule, cannot be solved within the framework of classical design approaches. Therefore, a crucial problem is the development of novel methods for simulation of structures with dry friction dampers allowing finding optimal design solutions to minimize dynamic and seismic impacts.
