In order to investigate the upgrading effects of punching shear capacity for RC slabs reinforced with AFRPs, static loading tests for the RC slabs were conducted taking reinforcing way and tensile stiffness of AFRPs as variable. Here, two reinforcing ways were applied which are of bonding cross-directional AFRPs and of bonding unidirectional one in a cross at certain intervals. The results obtained from this study are as follows; 1) when a magnitude of tensile stiffness of AFRPs is large, reinforcing effects in case using cross-directional sheet are superior to those in case using unidirectional one, 2) the larger the tensile stiffness of AFRPs, the larger the punching shear capacity is, 3) however, the capacity intends to be a maximum value and then to be decreased with increasing in its tensile stiffness; and 4) the capacity estimated by using proposed method corresponds to experimental one very well.
