METHOD FOR TESTING A STRUCTURAL STRUCTURE IN EXCESS IMPACT ACTION Russian patent published in 2019 - IPC G01M7/08 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in testing elements or structures of buildings and structures with numerical evaluation of stress-strain state of structure under action of above-normal short-term dynamic loads. When implementing the method, the tested structure is exposed to an overstock impact and the beginning and the end of the impact action are fixed. Instantaneous values of short-term dynamic load are measured using a force meter in a fixed time interval. Instantaneous values of accelerations and displacements of the building structure along its length are measured. Force of inertia is determined in fixed time interval proceeding from number of accelerometers, masses of sections and accelerations corresponding to arrangement of accelerometers. Instantaneous values of short-term dynamic load and value of inertial force are used to define force directed to deformation of structure, state of building structure is evaluated by average deformation energy. For more visual representation of stressed-deformed state of structure at over-standard impact action, diagrams reflecting dependences of instantaneous values of short-term dynamic load are plotted, inertia force, force directed to deformation of structure and averaged deformation energy against time.

EFFECT: technical result consists in determination of averaged energy of structure deformation at above-standard impact action.
