A Tower Test Station (TTS) of over head power lines (OHPL) supports and tower structures at Donbas National Academy of Civil Engineering and Architecture (DonNACEA) founded in 1997. TTS is intended for experimental studying and control of different types of OHPL supports and tower structures, and also for mechanical certification tests for an unification of new supports and foundations designs, according to international standards requirements. Researches and tests can be execut for another types of building structures, if its can be install to the force field and fit into the space served by the traction elements. Technical capabilities off TTS specified in this paper, isn’t ultimate, depend of testing structures they can be changed to the increasing direction. TTS is a part of the test center building products, constructions and structures of DonNACEA. During project of TTS have taken into account of powerlines structures development trends and the prospect of expanding its technical capabilities. By most technical indices TTS of DonNACEA exceeds the highest world Tower Test Stations. The TTS project, the testing program and tests control system designed according to international standard IEC-652. To a composition of the TTS includes universal testing hall intended for test the of individual structures and their fragments, and also alaboratory for mechanical testing of metal, building materials and structures. From 1997 to 2013 год at the TTS of DonNACEA performed series tests for different countries of the world, and a wide range of scientific experimental researches of tower structures
