| Abstract: | This paper introduces the investigation of the complete stress-strain curves of concrete underhigh temperatures from 100t to 600t, 44 prism specimens(100mm x 100mm x 315mm) were tested, and the staged characteristics of stress-strain curves Of concrete subjected to high temperaturewere analyzed with difference Of deformation properties between concrete under ordinals temperatareand those under high temperatures pointed out. Finally, the generalized stress-strain analyticalexpression was established. |

| Keywords: | high temperature complete stress-strain curves deformation characteristics |
