RESEARCH OF THE WORK OF REINFORCED CONCRETE BENDED ELEMENTS WITH THE USE OF POST-TENSIONED ROPES
The study of full-scale samples of bent reinforced concrete beams using tensioned ropes in a synthetic shell filled with grease is considered in the article. The purpose of the research is to test reinforced concrete beams using post-tensioned ropes to assess the load-bearing capacity and stiffness. Experimental results of studies on bent samples with rope tension and without ropes are presented. The study on full-scale samples revealed a number of features of the work of bent beams with post-tensioned ropes. The use of a post-tensioned rope without coupling with concrete allows for a more evenly distributed development of normal cracks and reduces the width of the crack opening. Pre-tension cable reinforcement increases the load carrying capacity of the area of the transverse bend.
