Abstract |
|
Physical experiments with large-scale models of engineering structures provide invaluable information for understanding the deformation processes in objects of complex configuration and allow researchers to reproduce the interactions between the structural elements on different scales. The article presents test stand designed and assembled at the Institute of Continuum Media Mechanics (Perm, Russia). Using this stand, studies of deformation processes in a large-scale model concrete structure were carried out. The deformation response of structural elements to the locally applied quasistatic and impulse loads was studied. The patterns of the spatial-temporal distribution of deformation parameters over the structural elements were obtained. The tests conducted in the elastic deformation mode allowed to obtain the vibration portrait of the structure, which provided basic information for the future experiments aimed at studying inelastic deformation of the structure until its ultimate failure. |
