Abstract

Abstract

In order to study the anti-penetration performance of concrete-filled steel tube (CFST) with honeycomb structure, six experiments on anti-penetration of the CFST with honeycomb structure were conducted by using a 125-mm smooth bore gun. The failure pattern and penetration depth of the targets under different working conditions were measured, and the typical failure modes of the CFST with honeycomb structure were analyzed. The differences of the failure pattern of the targets under different target-to-projectile size ratios were compared, while the influences of the impact point and steel tube wall thickness on the anti-penetration performance of the CFST with honeycomb structure were explored. Uniaxial compression tests on seven groups of hexagonal concrete-filled steel tube columns with different wall thicknesses and three groups of hexagonal concrete columns were carried out. The enhancement effects of the hexagonal steel tube on the strength and ductility of the core concrete under different wall thicknesses were studied, and the relationship between the strength enhancement coefficient of the core concrete and the hoop coefficient was obtained by data fitting. By refining the empirical formula for calculating the penetration depth of ordinary concrete, the formula for calculating the maximum penetration depth of the CFST targets with honeycomb structure was given. The results show that the wall thickness is an important factor that affects penetration depth, that is, the greater the wall thickness, the smaller the penetration depth. The locations of impact points have a great influence on the failure pattern of the target surface, but the influences of the locations of impact points on the penetration depth are complex. The existence of the steel tube can effectively increase the strength and ductility of the core concrete. The refined penetration depth formula can predict the maximum penetration depths of the projectiles to the CFST targets with honeycomb structure.
