DEFINITION OF cross-section area of PRINCIPAL reinforcement barS AT THE CONTROL OF reinforced concrete beams by the staTic and dYnamic METHODS
The article examines the results of theoretical and experimental investigations for evaluation of cross-section area of longitudinal reinforcement bar in reinforced concrete beams by the static and dynamic tests. By the investigations results is proved that cross-section area of longitudinal reinforcement bar in reinforced concrete beam is functionally connected with the main frequency oscillations and the maximum deflection of the beam, therefore the maximum deflection and the main frequency of vibration can be used as criteria to assess the area of cross-section area of longitudinal reinforcement bar.
