INVESTIGATION ON LOCAL DAMAGE OF REINFORCED CONCRETE PANEL IMPACTED BY HEMISPHERICAL SOFT PROJECTILE

Abstract

Most studies on local damage of reinforced concrete (RC) panel structures subjected to projectile impact have focused on normal impact, and only few studies have focused on oblique impact. Thus, we conducted impact tests under different impact conditions including oblique impacts so as to confirm the different impact behaviors of the RC panel structure. This study aimed to develop an analytical method by examining the test results and analytical conditions, and validate the proposed method through comparison of the test results.

We focus on the scabbing damage which is one of the local damage modes of RC panel and intend to investigate the relationship between the damage criterion and scabbing occurrence based on oblique impact test results due to soft projectile with hemispherical nose shape.
