In this paper, we discuss the result of the static collapse test of the asymmetric top hatted rectangular tube. The result includes collapse mode, maximum load, and absorbed energy. Five types of asymmetric top hatted rectangular tube were used Two types of tube with laser welded are different in their flange length. Three types of tube with spot welded have different distances between the spot welding points. From the experimental results, we investigate the characteristics of energy absorption and collapse mode of each specimen type. And we discuss the uncertainty of energy absorption following the irregular collapse mode. Finally, in designing the asymmetric top hatted rectangular tube, we discuss how to consider the uncertainties of the collapse modes and absorbed energy during the static collapse.
