Internally unreinforced slabs made of UHPFC and SHCC were able to avoid punching shear failure and collapse in a ductile bending pattern due to the high compressive and tensile strength of these types of concrete. The proposed analytical method succeeded in predicting the collapse lo...
Shear mechanisms generally govern the behaviour of reinforced concrete structures subjected to localised impact loads. Existing experimental results investigating punching shear in flat slabs subjected to impact loading shows that when increasing the loading rate, the punching shear strength also increases whe...
One interesting thing to note is that I checked the punching shear formula in the "Plain Concrete" section of the standard (ie. unreinforced concrete) and it simply applies a 2/3 factor to the regular punching shear formulas. So I guess this gives us an idea of the increase in strength ...
To study slab modeling validation a strengthened concrete tested by Agbossou et al. (2013) has been modeled. Square slabs in that study had the dimensions of 1250 × 1250 mm with a thickness of 100 mm. To prevent bending failure and punching shear failure in the above-mentioned study, high...
The GFRP nut and bolt did not strengthen the connection, and, in fact, decreased its overall strength when compared to the unreinforced specimen. The presence of the GFRP shear bolts also increased the connection ductility and the deflection capability. In the pseudo-dynamic tests the GFRP shear...
