The dependence of the bearing capacity on the class of concrete on the example of flexible reinforced concrete columns with combined reinforcement
Incoming article date: 15.09.2020The search for the most efficient and cost-effective materials and structures is an important and urgent task. Reducing steel consumption can significantly affect the cost of structures, and the use of high-strength steel is one such method. Currently, there is great interest in reinforced concrete structures, which contain various combinations of pre-compressed, pre-tensioned and non-tensioned reinforcement. To determine the dependence of the bearing capacity on the class of concrete using the example of flexible reinforced concrete columns with combined reinforcement, a numerical experiment was performed. The performed numerical experiment showed the feasibility of using combined reinforcement - all the racks considered in the experiment with combined reinforcement are more effective than racks with non-tensioned reinforcement. At the same time, depending on the relative eccentricity of external forces and flexibility, it is necessary to choose the most effective type of combined reinforcement.
