| Abstract: | An experimental research is carried out on high temperature behaviour of the bond-slip between concrete and a kind of profiled steel sheet,which is widely used in China.It is found that the bond strength between profiled steel sheet and concrete degrades greatly with the increase of temperature.A regressive formula is concluded from the experimental data to calculated the bond strength between profiled steel sheet and concrete at elevated temperatures. |
