| 摘 要： | 讨论了混凝土化学植筋的基本破坏形态,对常见的锥体-黏结复合破坏机理进行了分析;应用莫尔强度理论对混凝土锥体破坏面建立了混凝土抗拔力与锥体高度和混凝土强度的定量关系,基于黏结破坏的试验数据,通过数理统计得出极限平均黏结应力公式,最终建立了极限平衡状态下的承载力公式。进而通过实验数据证实了公式的可靠性,为混凝土植筋的设计计算提供了参考。

| Abstract: | Four basic failure modes for adhesively bonded rebar in concrete are discussed.Based on the Mohr theory,the relationship between the concrete strength and the height of the concrete cone and the resistance of the concrete is derived.Based on the test data for the bond failure,a formula is set up statistically.According to the force equilibrium a formula for the mixed-cone failure is obtained which is verified by the experiment date that the calculation results have good accordance with test results.The formula presented can be used in the practice design and construction. |
