Abstract

The results of experimental data of studies of reinforced concrete structures made of light high-strength concrete in a wide range of reinforcement coefficients (0.015-0.036) are presented. Experimental studies of a series of beam-type reinforced concrete structures made of light high-strength concrete were carried out according to the first and second groups of limiting states to substantiate the use of such structures in hydraulic engineering. It should be noted that the complex technical solutions for a floating bulkhead are under development for the construction of a gravity-type foundation (including an abutment in an earth dam). Recommendations on the use of the obtained results of experimental studies in hydraulic engineering building including when designing a reinforced concrete structure of a dry floating bulkhead for the construction of a gravity-type foundation made of lightweight high-strength concrete are given.
