Definition of cross-section area of longitudinal reinforcement bar in reinforced concrete beams by vibration method
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 main frequency lateral and longitudinal oscillations by the 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 lateral and longitudinal oscillations of the beam and construct the corresponding approximating functions, allow to receive the cross-section area of longitudinal reinforcement bar for a particular type of beams.
