FIELD: construction.
SUBSTANCE: invention relates to construction, namely to mechanical tests of materials, in particular to testing methods for building constructions, and may be used for testing the bending of beam constructions. Essence: the controlled cyclic load is applied to the sample and by the loading or unloading rate, and its magnitude, the selected parameters of loading are maintained at the predetermined time interval. Range and place of application of loads is regulated by the loading device and power device, and the strength and deformation parameters of the test structure are measured in the given time interval. Device contains the supports for the placement of the test specimen fixed in the reinforced floor, loading device with the power device. Loading device is designed in the form of, at least, one lever and the power device is designed in the form of cargo tank, which is positioned on each lever of loading device and designed with possibility to fill it with liquid.
EFFECT: possibility to evaluate the strength and operating parameters of flexible constructions in real modes of load measurement during operation after the complete and partial unloading.
