Effect of Shot Peening on Dynamic Buckling Critical Load Parameter Produced for Carbon Steel Columns


This paper has investigated the comparison of column buckling behavior between experimental results of medium carbon steel CK35 and Hong model. These columns are tested under dynamic buckling with and without shot peening. This comparison showed a good correlation and conservative for the columns. The maximum difference in percentage was about 10%. The above comparison involved initial imperfection, load duration and slenderness ratio of columns. The results indicated that the Hong model was capable of predict the dynamic buckling behavior of Ck35 columns.
