STRENGTH OF CENTRALLY COMPRESSED PIPE ELEMENTS OF IMPROVED DESIGN

Abstract

The purpose of this work was to identify the main problems associated with their compliance. Experimental studies of the strength of such elements. It turned out that, before the compression of the concrete core and the placement of a high-strength longitudinal reinforcement in it, it was possible to obtain a breakthrough of the investigated samples. Strength of improved samples compared with pipe-type samples of the classical design increased by 30 ÷ 50%. The above formulas are applicable for calculating the strength of both pre-compressed and uncompressed pipe-concrete elements.
