高温后横压力对钢筋与高强混凝土间黏结影响
Effect of Transverse Pressure on Bond Between Bars and HSC After Elevated Temperatures
摘要
Abstract
Cube specimens and special bond specimens were designed and cast with C100 high-strength concrete (HSC). Residual compressive strength of concrete cubes as well as bond strength based on damage testing was examined after being exposed to 200, 300, 400, 600, 800 ℃, and the relationship between the transverse pressure and the bond strength was explored. Furthermore, the detailed investigations were carried out on the appearance characteristics of specimens and degradation mechanism of bond strength, which could provide technical support and theoretical basis for both evaluating and strengthening the HSC structure after fire.关键词
