The ability of steel-concrete-steel sandwich tubes to resist local lateral loads has been investigated experimentally. Two types of loading were employed: quasi-static, by means of a 12.7 mm diameter hemispherically tipped punch, and dynamic, by means of a 12.7 mm diameter hemispherically tipped projectile fired from a compressed air gun. The performance of tubes with skin thicknesses of 1 mm and filler thicknesses of 10, 20 and 38 mm was measured in terms of energy absorption capabilities and compared with the equivalent performance of monolithic steel tubes.
