Prefabricated multi-story structure exposed to engineering seismicity

The paper presents results of an experimental and theoretical analysis of the response of a prefabricated wall structure of a multi-story building to technical seismicity effects. The experimental investigation employed a model of a seven-story carrying prefabricated wall structure of a prefabricated panel building in the scale of 1:3. The model of the prefabricated structure was gradually exposed to eight loading states, including the cyclic and monotonously rising loading. The cyclic load induced by Tira-vib electrodynamic exciter simulated technical seismicity effects. The drop of stiffness of the prefabricated system was monitored in the first place by measuring relative displacements between the wall units and the deformation of the whole system in horizontal, as well as vertical direction.
