The research on bearing capacity of supports with annular section

摘要

Our research work on the physical and mechanical properties of centrifuged concrete,the strength and deformability of cylindrical and conical transmission towers made it possible to reveal some incorrect calculations according to the old and new standards.To identify discrepancies in the calculations for the supports with annular section according to the SNiP 2.03.01-84 and according to the SP 63.13330.2012,we carried out the numerical experiments on the example of the transmission tower supports.As the test sample,the cylindrical transmission tower according to the Certification System GOST 22687.2
