Dynamic Response Analysis for Rigid Steel Portal Frames under Impact Loading

Abstract:

In order to improve our basic understanding of the impact-resistant behavior of steelstructures, three-dimensional elasto-plastic FE analysis was conducted for steel portal framesunder impact loading. Here, two rigid portal frames of diﬀerent column size were numericallyanalyzed taking the impact velocity of the falling weight as variable. The results obtained fromthis study are as follows: 1) maximum displacement of the frame increases linearly with eachincrement of the input impact energy; and 2) the bending moment distribution of the wholeframe at the time when the maximum response displacement occurs is similar to that understatic loading.
