Abstract
A computational analysis is presented to predict the ultimate and cracking shear strength of steel fiber reinforced concrete slabs. Different models are suggested considering the effect of concrete compressive and tensile strength, amount of flexural reinforcements, yield strength of the reinforcement bars and steel fiber properties (volume percent, aspect ratio, and type of steel fibers). The predicted results are compared with the experimental data found in literature and found good agreement.
Highlights
The Flat plate slabs defined as a structural member which carried directly by the columns without beams or girders
Yitiaki [4] presented a correlation between the punching resistance and flexural strength of slabs, he showed that the punching shear strength depends mainly on the yield strength of reinforcement and compressive strengthened concrete
The results indicate that the increasing of steel fiber content or thickness of the slab leads to increasing in punching shear strength and ductility of the slabs
Summary
The Flat plate slabs defined as a structural member which carried directly by the columns without beams or girders. Such type of structure has more space in addition to its pleasant appearance. Many other benefits arise from using steel fibers such as shear reinforcement in flat plates instead of the conventional shear reinforcement [3]. Different types of models or equations are proposed based on linear and nonlinear regression analysis to study the effect of steel fibers, flexural reinforcement and concrete properties on the ultimate and cracking shear strength of steel fiber reinforced concrete slabs
