C100 high strength concrete(HSC) was prepared. Compressive strength of HSC as well as shear bond strength and friction coefficient between HSC and rolled steel plate were tested after the specimens were exposed to elevated temperatures. The variation of compressive strength, shear bond strength and friction coefficient were analyzed from the view points of damage evolution for the meso and micro structure of concrete after exposure in different elevated temperatures. The results show that the compressive strength of HSC drops significantly when the temperature is higher than 400℃. The shear bond strength between HSC and rolled steel plate keeps a linear decrease with increasing temperature. The static and dynamic friction coefficient between HSC and HSC is 0.50.6, while the static and dynamic friction coefficient between HSC and rolled steel plate is 0.250.35.
