Response of Reinforced Concrete Columns Subjected to Underwater Explosions
Publication: Structures Congress 2023
ABSTRACT
Published research on the response of civil engineering structures subjected to underwater explosions (UNDEX) is relatively scant when compared to response for air blast. This paper presents preliminary assessment of the response of reinforced columns subjected to underwater explosions. The physical phenomena of underwater explosion and its effects are discussed. This is followed by a short summary on publicly available small-scale experiments conducted on reinforced concrete columns subjected to UNDEX and used as benchmark in this study. Peak blast pressures measured from the experimental tests are compared with those obtained from legacy empirical equations with proper magnification factors. The concrete damage plasticity (CDP) model used for analyzing structural response of the columns in a finite element program and its calibration are discussed.
