Analysis of the influence of design parameters of the unit on the concentration of forces in the support zones of flat reinforced concrete floors at the ends of the walls
Incoming article date: 07.02.2025When designing flat reinforced concrete slabs, the most complex and responsible structural unit is the area where the slab is supported by the columns and walls. This is due to the action of large concentrated efforts and the greatest density of reinforcement. In view of this, the issue of choosing calculation methods that most accurately estimate the punching capacity for suchstructural units is relevant. With an increase in the ratio of the dimensions of the sides of the pushing structure, the force ceases to be distributed uniformly along the pushing contour and a concentration of forces occurs near the short side. This article is devoted to the evaluation of the results of finite element modeling and calculations of the bearing capacity for pushing in the area of the end of the pier, analysis of the influence of the floor thickness, the dimensions of the pier and the class of concrete on the concentration of pushing forces in the floor near the end of the pier.
