This study investigates the punching shear strength and failure behavior of reinforced concrete slabs strengthened with glass fiber-reinforced polymer GFRP la. This paper discusses the influence of steel fiber in both punching strength of flat slabs and shear strength of concrete beams. DI Jürgen Mandl MSc. A method of evaluation of the punching strength of reinforced concrete slabs is presented and the correlation between punching resistance and flexural strength clearly established. The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity which may be increased with addition of traditional fitments such as reinforcing steel. Steel fiber reinforcement concrete SFRC is considered as a method of strengthening structural elements such as flat slabs and it was used to enhance flexural strength and punching shear strength of the concrete slabs.
The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity which may be increased with addition of traditional fitments such as reinforcing steel headed studs or shear heads.
A total of twelve small-scale flat slabs of different dimensions that. Punching shear strength of balanced slab-column connections made of two grades of Recycled Aggregate Concrete RAC with each grade containing. However the combination of steel fibre reinforced concrete and conventional reinforcement has in many researches shown to emphasize good bearing capacity. Each of 14 square slabs was simply supported along four edges and loaded to failure under a concentrated load over a square area at the center. Adding from 30 to 60 kgm3 steel fibers to concrete increase the punching shear resistance from 162 to 398 for slabs in group A. See that steel fibers increase considerably punching shear capacity of slabs and this increase is directly proportional to fiber volume.
