Application of Full-scale Experiments for Structural Study of High-rise Buildings

The paper presents the application of full-scale-model experiments to develop software and design a device for determining the degree of reinforcement bar rusting in concrete elements of high-rise buildings. Operation of the designed device is based on the dependence of the electromagnetic field surrounding a ferromagnetic body on its geometrical parameters and reduction of electromagnetic properties of the ferromagnet by oxidation. To receive primary information about the electromagnetic field an original measuring device is used, which is a matrix of high-precision electromagnetic transducers. In order to determine their position in relation to the control object distance sensors are used. The measurement results are transmitted to a computer model that is adjusted so that the results of modeling the electromagnetic field at the locations of transducers agreed with the results of direct measurements. The required model parameters are the geometric dimensions of the reinforced bar.To raise the measuring device to the height of the building structure it is proposed to install it on a quadrotor.
