| 摘 要： | 设计了专用的升温装置和加载装置,通过中心拔出试验,对高温中和高温后经历不同受热温度和加载路径的钢筋与混凝土进行粘结-滑移拔出试验,分析了高温下钢筋与混凝土粘结性能退化机理。研究表明,高温后试件的粘结强度比高温中试件下降较快,但达极限粘结应力时其滑移量相对高温中试件较小。在恒载升温条件下,当达到一定温度时,钢筋与混凝土的滑移进入急剧增长阶段。 |
| 关 键 词： | 高温 钢筋 混凝土 粘结性能 |

| 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. |
| Keywords: | high temperature reinforcement concrete bond property |
