Abstract

This study focuses on the numerical investigation of the sliding response of flexible structures, simulating school buildings located in Nepal. A deformable granular layer is proposed for the seismic isolation of these structures, aiming at the reduction of their seismic damage. The displacement and acceleration response of the isolated structure is investigated for a wide range of analytical pulse ground motion excitations and one recorded ground motion excitation. The seismic behaviour of the deformable granular layer is compared to the behaviour of a rigid-plastic sliding layer of the same strength. The increased energy dissipation of the deformable sliding layer that emerges from its oscillation before sliding can lead to a significant reduction of the acceleration of the isolated structure.
