| Abstract: | The test of concrete under high temperature and the test phenomenon is introduced. Based on the test of mechanical behavior of concrete subjected to fire, the residual compressive strength of concrete after high temperature is obtained. 4 kind of formula for the residual compressive strength of concrete after high temperature are synthesized and compared with the result from the experiment, the comparative coherent formula is found. |
