Over the past few years, several studies have been made on fracture analysis of concrete structures by the distinct element method. But little attention has been given to the analysis of concrete structures subjected to high speed load. It has been reported by several experimental researches that the maximum strength and the stiffness of concrete material becomes larger as the speed of the applied load becomes faster. Therefore, the objective of this study is to simulate the fracture behavior of concrete column under high speed load by 3-D distinct element method. In this analysis, bi-linear elastic plastic theory in compressive, tension-softening model in tension and Mohr-Coulomb yield criterion are employed to represent properties of concrete. Referring to the results of high speed loading test and considering the increase of the yield stress, the analytical result of the load-deformation relationship is in good agreement with the test result. And this numerical simulation can mostly express the fracture behavior of concrete column, which is, scattering of fragments of broken concrete.
