Annotation: An experimental research complex of metal multifaceted poles’ (MMP) stress-strain state (SSS) is performed in two stages: the research of six natural structural of MMP with high H=7.5 и 10.5 m at the DonNACEA Tower Testing Station and a SSS laboratory studying of fragments natural structures of metal multifaceted poles. The purpose of experimental research at the 1st stage is to identify specific zones of poles’ probable destruction and deformability, at the 2nd stage – (considering to the first stage’s results) is determination the structure’s stress-strain state at the joint work of the octagonal pole’s fragment, and its base, and also verification of convergence results with theoretical assumptions. For the research we used the load tests method and the tensometry method of determining the stress strain in the structural body. Tests of natural structures performed according to a pre-designed program. For laboratory researches the special experimental stand has been designed. Ultimately determine the sufficient convergence of numerical and experimental studies’ results of the multifaceted poles’ SSS. So, the adequacy of finite element computational model for use in an engineering design has been confirmed.
