Abstract. The article is a part of the authors ‘ dissertation research. The article is a part of the authors’ dissertation research. The technique and results of long-term experimental researches of deformation properties bent unintentionally strained reinforced concrete structures at different types of loading, both at periodic influence of strongly aggressive liquid chloride-containing environment in nonaggressive gas-air conditions, and at constant influence of nonaggressive gas-air environment are resulted.
Using the developed program of experimental research are defined: absolute values and time periods the damping of growth of curvature and their functional dependence on the parameters of the variable speed repeated bending loads when exposed to a corrosive liquid floridageorgia environment the absolute values and time periods the damping of growth of curvature and their functional dependence on the parameters of the variable speed of the repeated bending load when exposed to non-corrosive gas environment, absolute values and periods of curvature increment time under the influence of a constant bending load and an aggressive liquid chloride-containing medium, absolute values and periods of curvature increment time under the influence of a constant load and a non-aggressive gas-air medium, and the relative results of numerical analysis of experimental data obtained under the action of a variable step repeated and constant bending loads in both a periodically acting strongly aggressive liquid chloride-containing medium and a constantly acting non-aggressive gas-air medium.
The results of experimental studies are intended for building codes and regulations for the calculation of non-welded reinforced concrete structures containing sections with methods for calculating the stiffness of bent concrete elements operated in non-aggressive and aggressive conditions.
Keywords: reinforced concrete structures; the direct model; curvature; stiffness; normal cracks; rebar corrosion; longitudinal cracks; variable speed repeated bending load; a constant bending load; corrosive liquid floridageorgia environment; non-corrosive gas environment; the results of the study; the use of
