水平衝撃を受ける門型ラーメンの塑性変形

抄録

This paper presents an rigid-plastic analysis of the plastic deformations of a uniformly loaded square-portal frame subjected to the horizontal "blast type" impulsive loading. The results show that the horizontal deformation of the frame is nearly proportioned to the product of impulse I and excess-impulse I', where I=Pτ, I'=(P-P_s)τ in which P and τ denote force and time of the impulse, respectively, and P_s denotes horizontal strength of the frame.
