Reinforced concrete beams subjected to moving cyclic loads has a reduced fatiguernlife as compared to that of fixed-point pulsating loading. Moving loads has morerndamaging effect to the concrete, this might cause brittle shear failure. rnrnIn this study experimental and analytical investigation was conducted on sixrnreinforced concrete beams without web reinforcements, to study the behavior ofrnshear fatigue in reinforced concrete beams subjected to moving loads. One beamrnwas made to fail monotonically to determine the static shear capacity. Three beamsrnwere subjected by a step wise moving load to 85%, 75% and 68% of the static shearrncapacity. The other two beams were subjected to a fixed-point pulsating load torn75% of the static shear capacity, but in different loading location (at midspan andrnat a location where the shear force to capacity ratio is maximum). Step wise movingrnload caused faster shear strength degradation compared to fixed pulsating load.rnRate of increase in residual deflections with number of load cycles in step wisernmoving loads is higher compared to stationary cyclic loading which shows higherrndamage accumulation more than that of fixed pulsating load. Crack formation andrnpropagation was monitored throughout the experimental programs by manuallyrnmarking when new cracks formed. In fatigue loading the major diagonal cracks inrnbeams are more horizontal than that of monotonic loading conditions. Dependingrnon the amplitude of loading it is difficult for diagonal cracks to propagate into therncompression zone in case of fatigue loading.
