Description:

Experiments aimed at monitoring the magnitude of climatic loads on building structures (wind, snow, temperature loads), diagnostics of building structures, tests carried out on physical models of building structures (laws of model similarity, simulation of earthquakes on shake tables, simulation of wind effects in wind tunnels, static load tests on physical models), monitoring of building structures, static load tests (civil engineering structures, industrial structures, bridge structures), dynamic load tests and dynamic informative tests (civil engineering structures, industrial structures, bridge structures, footbridges, effects of technical seismicity, assessment of adverse effects of vibrations on the human body, assessment of the effect of vibrations of the structure on installed technological equipment).
