MEAN CRUSHING STRENGTH OF CLOSED-HAT SECTION MEMBERS

This paper presents a method for approximately calculating the amount of energy absorption of closed-hat section members subjected to axial loading. The analytical relation by which the static mean crushing load is computed when a closed-hat section member is quasi-statically crushed was obtained by the method of limit analysis in consideration of a rolling action. Experimental verification indicates that this method of analysis is very effective. In order to examine the amount of energy absorption of a member under dynamic crushing load, dynamic crushing tests were performed on the same members, and the correlation between the static and the dynamic mean crushing loads was determined.
