Stress-strain state monitoring for the structures of the radio and television transmitting station in Vladikavkaz

Abstract

Introduction. The article presents data on the activities carried by the Research Institute of Building Constructions named after V.A. Koucherenko from July 2022 to March 2024 during the installation of a 210 m high radio and television transmitting tower in Vladikavkaz, Russian Federation. The most stressed structural elements located at 1.700 and 40.047 elevations were equipped with mechanical strain gauges to collect data on the stress-strain state of the whole structure. In addition, data of the geodetic survey performed during construction were analyzed.

Aim. To conduct stress-strain state monitoring according to the method developed by the Research Institute of Building Constructions named after V.A. Koucherenko for individual structures and critical components of an antenna tower, as well as for early warning and timely preventing possible emergency situations during its construction.

Materials and methods. The article presents drawings of metal structures and photographs of measuring instruments used during construction.

Results. Mechanical safety of the tower steel structures was ensured by monitoring the stresses of their most heavily loaded elements, as well as their movements and deformations.

Conclusions. The analysis of the stress-strain state measurements showed that the stresses and existing deviations of control points from the design position are within the permissible values specified in the regulatory documents in force on the territory of the Russian Federation.
