Former is to employ the test to prediction ratio and latter is newly suggested approach that can guarantee more reliable prediction considering the significant uncertainties to minimize the possibility of over-estimating punching shear strength. For comparative study, the selected test results and the ...
A Newtonion fluid is one in which the shear stress is linearly related to the shear rate. In a such a fluid, the viscosity for that fluid is a constant value. (In a non-Newtonian fluid, viscosity ends up being a dynamic function of another variable, such as time or force.) Not surp...
Punching shear failure of concrete slabs is brittle with very little warning, whether with or without membrane tensile forces. Tensile forces decrease the punching shear strength, which if not accounted for properly causes a premature failure. In addition, there is a lack of agreement between ...
The comparison procedure filters out joints with member (brace or chord) failure and punching shear failure. The numerical data obtained from the extensive, calibrated nonlinear FE study demonstrate the applicability of the new IIW equations to thick-walled joints.International symposium on tubular ...

The formulae for local and punching shear failure take account of deformation parameters as well as strength parameters. The stress-level dependency of the angle of shear resistance is also considered. Three formulae have been unified based on the conception of minimum resistance. The analytical ...
