摘要

The mechanics characteristics of high-strength concrete simple supported beams with three surfaces exposed to heat are investigated after experiencing different heating temperature and different cooling patterns. The influences on the compression strain, pulling strain and shear strain of high-strength concrete beams exposed to the high temperature are analyzed. The changing rule of the ultimate load and deflection of high-strength concrete beams after the high temperature is gained. The different high temperature properties between reinforcement concrete beam and high-strength concrete beam are analyzed.
