Description

Structural behavior and residual structural capacity of 2-way reinforce concrete (RC) slabs against punching shear failure were investigated through static loading tests after falling-weight impact loading tests. It was found that punching shear capacity of RC slabs damaged by repeated impact loads slightly decreases compared with non-damaged slabs just before the occurrence of punching shear crack. It was also found that punching shear capacity rapidly declines after formation of cracks due to punching shear at the bottom surface of the slabs. Based on the test results, the method to evaluate punching shear resistance of RC slabs subjected to repeated impact loads was proposed. Furthermore, the applicability of the proposed method to 1-way slab was examined.
