Non-Linear Analysis of Flat Slabs Prestressed with Unbonded Tendons Submitted to Punching Shear

نویسندگان

چکیده

This article describes a numerical study for the evaluation of punching shear behavior non-adherent prestressed flat slabs without reinforcement. Nonlinear three-dimensional models were used, along with finite element method (FEA) through ATENA software in order to validate constitutive adopted concrete and steel. The results compared experimental results. revealed good agreement among load capacity, deformations, cracking panorama, as well relation between failure loads. After validation, parametric was carried out analyze influence tendon spacing, slab thickness, column rectangularity slabs. Finally, obtained estimated values according main normative predictions dealing system.

Numerical Analysis of Punching Shear Failure of Reinforced Concrete Slabs

Nearly no load bearing behaviour of reinforced concrete members allows such varied interpretations and complex discussions as the shear behaviour. Especially the three-dimensional problem of the punching shear failure of reinforced concrete members is internationally discussed. Nevertheless up to now, there is no unified design approach or even an overall accepted design model. Especially for l...

Punching shear strength of steel fibre reinforced 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. In addition to these traditional methods of strengthening against punching, steel fibre reinforcement has proved to be an effective and viable alternative. The addition of fi...
