EXPERIMENTAL STUDIES OF THE COUPLING STRENGTH OF REINFORCEMENT WITH CEMENT-SAND CONCRETE
Abstract and keywords
Abstract (English):
The coupling of concrete with fiberglass reinforcement at different values of its diameter and depth of sealing is investigated. The difference in the distribution of tangent stresses over the depth of reinforcement bars‘ sealing is determined due to their diameters, which is reflected in the nature of the destruction of fiberglass reinforcement when it is pulled out of concrete. The values of correction coefficients that take into account the dependence of the fullness of the tangent stress plot in the sealing area on the diameter of the reinforcing bar are determined. Recommendations for calculating the base length of the fiberglass reinforcement anchorage in concrete are given.
