This paper presents an analysis of variable parameters on the shear capacity of elements reinforced with FRP bars: longitudinal reinforcement ratio; transverse reinforcement ratio; axial stiffness of reinforcement; shear slenderness; concrete compressive strength; spacing of stirrups; depth; shape of beam cross-section; inclination of transverse reinforcement and bond behaviour of stirrups.

W artykule przedstawiono analizę parametrów zmiennych na nośność na ścinanie elementów zbrojonych prętami FRP: stopnia zbrojenia podłużnego; stopnia zbrojenia poprzecznego; sztywności osiowej zbrojenia; smukłości ścinania; wytrzymałości betonu na ściskanie; rozstawu strzemion; wysokości użytecznej; kształtu przekroju poprzecznego belki; nachylenia zbrojenia poprzecznego oraz przyczepności strzemion.
