Abstract: The beneficial effects of using HPFRCC materials in structural members that experience high shear forces have been experimentally verified in numerous investigations. These effects are particularly advantageous in seismic resistant structures, which undergo relatively large shear reversals under seismic excitation. It has been demonstrated that the substitution of concrete with HPFRCC at locations of the structure with high deformation demands leads to a significant qualitative improvement of their structural behavior. The improvements are characterized by an increased resistance to brittle failure modes, such a shear failure and bond splitting failure, a confinement effect of the HPFRCC at large deformation levels, as well as high damage tolerance.
The discussions in Task Group E on the topic of Seismic Design, Shear and Torsion identified shear as the governing mechanism for these types of loading. While the ultimate goal of the activities in Task Group E is to develop a seismic design methodology for structural members using HPFRCC including shear design, the subsequent discussion focused on the response of HPFRCC to shear.
