The aim of this research is to present correction factors for the punching shear formulas of ACI-318 and EC2 design codes to adopt the punching capacity of post tensioned ultra-high-performance concrete (PT-UHPC) flat slabs. To achieve that goal, the results of previously tested PT-UHPC flat...

The proposed new formula exhibits the most accurate test to prediction ratio among the existing formulas. Furthermore, it renders the lowest probability of exceedance that the predicted punching shear strength exceeds the nominal punching shear strength. The proposed new formula can minimize the ...

For both small and medium joints, like the truss girders in this study, as well as for large joints, such as those in [26]), the Eurocode 3 formula closely estimates the punching shear resistance of the CFST joints, while the corresponding AWS D1.1 code formula yielded rather conservative...
On the basis of the test, the punching shear capacity formula of RAC slabs with and without steel fibres was proposed and discussed.doi:10.1007/s11709-018-0510-6Jianzhuang XIAOWan WANGZhengjiu ZHOUMathews M. TAWANASP Higher Education PressFrontiers of Structural and Civil Engineering...
