A NUMERICAL STUDY ON THE MITIGATION EFFECTS BY ARAMID FIBER SHEET REINFORCEMENT ON THE SCABBING OF RC SLABS

Abstract

In recent years, tornado and volcanic eruption have increased under the influence of climate change and crustal movement. In the events, collision of tornado missiles and volcano cinder with the important structures such as atomic energy facilities is concerned. This study conducted numerical analysis of the previous experiment conducted by the authors and investigated the mitigation effects by the aramid fiber sheets attached on the back surface of RC slabs. Numerical results reproduced the mitigation effect by the fiber sheet reinforcement and discussed the mitigation mechanism.
