Abstract

Abstract

Special temperature rising system and loading system were designed. Through the centrally pullout test, it was measured that the bond- slip performance of reinforced concrete under different temperatures and different loading ways at and after high temperature. The deterioration mechanism of bond in reinforced concrete was analyzed the investigation shows that the bond strength degrades more greatly after high temperature than at high temperature, and the slippage at the ultimate bond strength is smaller than the latter. When the temperature reached a certain value at constant load, the slippage in reinforced concrete increases sharply.
