Monitoring of the elements stability of building constructions by means of example of vertical elastic rod of high flexibility

The article is related to the field of geodetic and engineering construction monitoring of building structures in the form of rod systems. It investigates the measurement accuracy of the compression deformation of the rod. As an example, there is considered a vertical rectilinear rod of high flexibility, loaded with a longitudinal axial force. There is explained the accuracy with which it is necessary to measure the displacement of the rod end during the deformation. There is laid out the calculation of the maximum stress deviation based on the stability and flexibility of the rod.
