Abstract
In order to understand the energy absorption characteristics of various types of steel tubes and provide certain basis for model selection in the engineering application, this paper adopts the experimental study to conduct the comparative study on lateral quasi-static compression energy absorption characteristics of three types of steel tubes, i.e. round steel tube, square steel tube and hexagonal steel tube. Through analysis of the test phenomenon, the total energy absorbed by equal deformation and the energy absorbed per unit mass, the result shows that the steel tube with hexagonal cross section is provided with such advantages as steady absorption, stable deformation mode and high energy absorption ratio, and is more suitable for application in engineering than the round steel tube and the square steel tube.
