Originální abstrakt

Concrete structures are loaded during their lifetime. These structures are loaded and unloaded i.e. loading stressed structure as cyclically loaded. This paper is concerned with the acoustic emission method used to detect the forming cracks. The detection by the acoustic emission method is based on recording the elastic waves formed by active cracks. The loading frequency of the concrete beams tested was 2 Hz. Measurement started with a loading force of 30 kN being increased in 5 kN steps to the final value of 70 kN for 1 hour. The whole experiment contains about 72,000 cycles, i.e., the loading and unloading of the concrete structure. The paper describes the application of the acoustic emission method to this concrete beam at cyclic loading.
