BADANIE MODALNE ZAMODELOWANEGO ELEMENTU METALOWEGO O STRUKTURZE KRATOWNICOWEJ

Abstract

The article exams the walls of a reinforced concrete chimney with a rectangular cross-section in Huta Częstochowa. A Ferroscan Hilti FS10 was used for the test. An example protocol of the results obtained from the device and several graphical images of the reinforcement signal are presented. Despite significant wall damage, the measurements were carried out with success. An orthogonal reinforcement solution was found. Bars in both directions differ significantly in diameter. Considerable density changes of the reinforcement in the corner zone were recorded in both the vertical and horizontal direction. As a result of the test, considerable carelessness in the reinforcement execution was observed, which manifested in a variety of cover and deviation of the reinforcement direction from the designed one. The conclusions state that a control forging the concrete up to the reinforcement and measuring the diameter of the reinforcement is necessary for the proper testing of the reinforcement using the electromagnetic method.
