FIELD: test equipment.
SUBSTANCE: invention relates to the field of testing equipment, in particular to the safety of buildings in emergency conditions, and can be used to determine failure of structural systems of a reinforced concrete building in fire conditions and to identify the weakest elements of reinforced concrete structures of a building under action of power loads and high temperatures. Method includes simultaneous testing of reinforced concrete sample by power and fire load in fire test furnace before failure of structure, at that two to four samples are simultaneously tested. Latter are installed close to each other but do not communicate with each other; each sample has a slab and beam part; samples are supported by a reinforced concrete column, which transmits load on a reinforced concrete foundation, which is installed on the floor inside the fire space of the furnace. In the beginning, the load is supplied to the samples (except one), then the specimens fire load is performed till the specific state (destruction) is achieved.
EFFECT: possibility of performing tests close to real ones, providing complete and continuous monitoring of condition of building structures during tests, obtaining prompt and reliable evaluation as per results of tests, reduction of labor costs, material consumption during tests.
