Web75 mm. The punching shear reinforcement at the corners of the slab consisted of 60 mm deep steel C-shapes. The C-sections were with stirrups of 6 mm diameter spaced 75 mm. Fig. 1 shows the geometry and reinforcing details. The average yield stress,/s, of the reinforcing steel was 467 MPa, while the aver age concrete strength was fc = 23.5 MPa. WebMay 29, 2024 · The article handles potential approaches to design and determination of total load capacity of foundation slabs and floors. The research is focused on punching shear failure of reinforced ground supported slab. The article presents detailed results of the experiment made and advanced numerical modelling based on nonlinear analysis and … how does a power surge protector work

WebMay 11, 2024 · Once the moment has been determined, the design will proceed in a similar fashion for concrete slabs. The critical areas include flexural design, punching shear and … WebApr 10, 2024 · However, the American ACI code specifies that the first perimeter of punching reinforcement must be at a distance of less than 0.5d, so it seems appropriate to place the first perimeter between 0.3d and 0.5d from the edge of the loaded zone. Additionally, the EC-2 indicates that the distance between one perimeter and another must be less than 0 ... WebTen (10) high-strength concrete slabs reinforced with new type of steel fibers, the double hooked-end steel fibers, were tested under punching shear loads. The strength of the concrete fc varied from 80 to 100 MPa. The fiber content Vf varied from zero to 1.2%. Two different values of flexural reinforcement ratios ρ (= As/bd) of 0.9% and 1.4% were chosen … phosphate calcium
