Abstract
The series of tests had been done in order to make resistant ability of steel tube member better against impact action as like a rock fall. Outside members were steel tubes in which were arranged by some small steel tubes and fulfilled by mortar around those tubes. Static loading tests and impact tests by the free fall of a heavy weight were achieved. Characteristics of those members had been investigated by results of tests and theoretical calculations using section sprit method. Finally, the equation to estimate the energy absorption of those steel tubes under impact concretely had been proposed.
