Abstract

For retrofitting structures against blast loads, sufficient ductility and strength should be provided by using high-performance materials such as fiber reinforced polymer (FRP) composites. The effectiveness of retrofit materials needs to be precisely evaluated for the retrofitting design based on the dynamic material responses under blast loads. In this study, refined FEM analysis with high-strain rate dependent material model and debonding failure model is conducted for evaluating the FRP retrofitting effectiveness. The structural behavior of reinforced concrete (RC) slab retrofitted with glass fiber reinforced polymer (GFRP) under blast pressure is simulated and the analysis results are verified with the previous experimental results.
