SHEAR STRENGTH OF REINFORCED CONCRETE CIRCULAR SLABS

Few studies on the shear strength of reinforced concrete circular slabs subjected to distributed loads have been reported.To evaluate the shear strength of such slabs. tests were conducted using test specimens in which parameters such as reinforcement ratio and diameter-to-depth ratio were varied. From the results, an evaluation method of shear strength was obtained and expressed in terms of moment-to-shear ratio, M/V·d, and radial and circumferential reinforcement ratios. Furthermore, the effect of shear reinforcement in the slabs was also investigated.
