САЖЕТАК / ABSTRACT:
Incorporating the possibility for rocking motion into the design of structures can contribute to their seismic resilience and improve their ability to withstand earthquake-induced forces. A review of the history of rocking motion analysis is done, both in terms of methods and practical implications. This is followed by a framework for the implementation of the Discrete Element Method (DEM) for rocking analysis of a rigid body as it can be carried out by the open-code software Yade. The clump feature on which the simulation is based is explained in detail. A rigid-body model of a typical Bulgarian reinforced concrete residential building was created and analyzed by Yade for three levels of ground motion with PGV of up to 2.1 m/s. The rocking response of the building and its dependence on the intensity of ground motion are successfully demonstrated.
