摘要：Problem formulation.Determination of the physical and mechanical characteristics of the material of structures using non-destructive methods is the basis for determining the technical condition of buildings and structures.The current regulatory documents do not clearly determine the orientation of the ultrasonic monitoring device during measurements,which affect the reliability of the methods used to determine the properties of the material in the used structures.Рurpose.To evaluate the effects of the orientation of device of ultrasound control during the determination of physical-mechanical characteristics in used structures and the possibility to improve these methods.The technique.Comparison of the performed measurements using ultrasonic devices in similar zones of typical structures,manufactured according to typical technologies operating under the same load and statistical processing of the obtained results (with visualization) was carried out using the software EXEL.The presentation material.During the process of performing tests,the results of visual ultrasound were tested: the ultrasound device was installed in a certain way,the parameters of the technology and operating technology are clear.For greater accuracy,the visualization of physical and mechanical characteristics for the additional method of ultrasonic control,it is necessary to consider in the case of inflows.Conclusions.During the measurements,the influence on the results of determination of the speed of ultrasound was confirmed: the direction in which the ultrasonic measuring device,the parameters of the production technology and the operating conditions are located.To improve the accuracy of determining the physical and mechanical characteristics using the method of ultrasonic control,it is necessary to take into account these effects.
