Concrete elements are often subjected to high compressive forces applied over small contact areas; the consequent load spreading can result in concrete crushing or splitting failures. The latter is due to cracking phenomena caused by tensile stresses perpendicular to the load. In the last decades Fibre Reinforced Concrete (FRC) has been widely studied for many applications (precast tunnel segments, retrofitting, slab, etc.) and different standards now include rules for FRC members. However, only few analytical models allow the calculation of splitting bearing capacity for FRC elements under concentrated loads. To this aim, a new analytical formulation is proposed which enables a good agreement with experimental results collected from the literature regarding FRC prisms exhibiting a splitting failure.

Abstract
Concrete elements are often subjected to high compressive forces applied over small contact areas; the consequent load spreading can result in concrete crushing or splitting failures. The latter is due to cracking phenomena caused by tensile stresses perpendicular to the load. In the last decades Fibre Reinforced Concrete (FRC) has been widely studied for many applications (precast tunnel segments, retrofitting, slab, etc.) and different standards now include rules for FRC members. However, only few analytical models allow the calculation of splitting bearing capacity for FRC elements under concentrated loads. To this aim, a new analytical formulation is proposed which enables a good agreement with experimental results collected from the literature regarding FRC prisms exhibiting a splitting failure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
