IPC: G01M7/08
Filed: 2018-12-18
Granted: 2019-08-28
Abstract: FIELD: construction. 
     SUBSTANCE: invention relates to construction and can be used in testing elements or structures of buildings and structures for evaluation of stress-strain state under action of excessive short-term dynamic loads. During the method implementation, evaluation is performed by means of comparative analysis of test results of tested structure on pliable supports and similar structure on rigid supports at equal test conditions. Both structures are exposed to an excessive impact action and the beginning and the end of 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 each 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 each structure, and value of averaged deformation energy is determined from it and average value of structure displacement in time. Energy ratio is calculated from the ratio of averaged energy values, which is used to determine reduction of active energy to the building structure using flexible supports. Based on the energy directed to deform the support, and the total energy acting on the structure and supports, the efficiency of pliant supports application is assessed. 
     EFFECT: possibility of evaluation of stress-strain state of structure on pliable supports.
