Punching Capacity of UHPC Post Tensioned Flat Slabs with and Without Shear Reinforcement: An Experimental Study

نویسندگان

چکیده

Punching capacity is one of the main items in design both pre-stressed and non-pre-stressed flat slabs. All international codes include provisions to prevent this type failure. Unfortunately, there no code provision for UHPC yet, hence, aim research experimentally investigate impact column dimensions punching reinforcement on post-tensioned slabs compare results with codes’ evaluate its validity. The test program included five a compressive strength 120 MPa: as control sample, two study effect size, last reinforcement. Comparing showed that ACI-318 more accurate an average deviation about 5%, while EC2 conservative 20%. Besides that, reduces size wedge by increasing crack angle 28° instead 22° without Also, assure ductility stiffness are enhanced increased ratio. Doi: 10.28991/CEJ-2023-09-03-06 Full Text: PDF

Estimation of Punching Shear Capacity of Concrete Slabs Using Data Mining Techniques

Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...

Numerical Simulation of Punching Shear of Flat Plates with Low Reinforcement

Abstract—Punching shear failure is usually the governing failure mode of flat plate structures. Punching failure is brittle in nature which induces more vulnerability to this type of structure. In the present study, a 3D finite element model of a flat plate with low reinforcement ratio and without any transverse reinforcement has been developed. Punching shear stress and the deflection data wer...

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...

Improving the Punching Shear Strength of RC Slabs by FRP and Steel Sheets

This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...
