本文提出了一种近似计算轴心荷载作用下封闭式截面杆件吸能量的方法。通过考虑滚动作用的极限分析方法，得到了闭合截面构件准静态受压时静力平均受压载荷的解析关系式。实验验证表明，该分析方法是非常有效的。为了考察构件在动态压碎载荷下的能量吸收情况，对同一构件进行了动态压碎试验，并确定了静态和动态平均压碎载荷之间的相关性。
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.
