Test procedures of aerial supports on the testing ground of Donbas national academy of civil engineering and architecture
Abstract: The paper has presented the test procedures of aerial supports on the testing ground of tests of overhead power lines and tower structures of the Donbas National Academy of Civil Engineering and Architecture. The following engineering research tasks: determination of the bearing capacity and deformability of the aerial supports under the effect of the glazed ice and wind attacks have been set up. The research object – a tetrahedral narrow-base support AO-60 with the Howe truss consisting of single angles – has been chosen. The aerial support has been the three-dimensional strut truss in the form of a rectilinear tetrahedral pyramid with the upper prism part of 1 m and with the height of 60 m. The detail drawings of the aerial support have been worked out at the Metal Structures Department of the Academy. The technique of test procedures of the aerial supports has been approved. The general scheme of the experimental plant and gauge length to study of the natural glazed ice and wind attacks has been offered. The given technique enables to provide the large-scale tests not only for the aerial supports but also for the power line supports, supportive and distributive devices, tower cranes to check the bearing capacity and deformability with real attached loads.
Keywords: aerial support, testing ground, technique, test, glazed ice and wind attacks, experimental plant, loading scheme, force, load, electrodynamometers.
