Abstract
This doctoral dissertation aims to evaluate the inelastic response of three-dimensional reinforced concrete structures in a state of progressive collapse. In addition, it is investigated at the same time the effect on the structural response of the infill walls, the deformability of the soil and the uncertainty due to the mechanical properties of the materials as well as to the seismic motions. Finally, the progressive collapse of structures under the action of multiple earthquakes is being considered. In the present study, the adopted models of progressive collapse are realistic since: (a) they are based on a reliable description of the failed members and not on their arbitrary removal, and b) the real 3D modeling and at the same time the three-dimensional seismic action. In the context of the dissertation, the progressive collapse is studied for repeated earthquakes and the question of critical parameters and how they affect the phenomenon of progressive collapse (material parameters, seismic records, infill-walls, soil-structure interaction, etc).
