| Abstract: | A simple calculation expression of the shearing flow and the coordinates of bending center is introduced for the thin- walled beam with open section. The method of graph multiplication can be used to calculate the coordinates of the bending center of the thin - walled beam with open section which consists of n small rectangles, thus avoiding complicated integrated operation. |

| Keywords: | thin-walled beam with open section coordinates of bending center shearing flow static moment |
