摘要
通过对45个试件进行拉拔试验,研究了混凝土强度、混凝土保护层厚度、钢筋的直径、钢筋的锚固长度以及横向配筋率等因素对HRB500钢筋机械锚固性能的影响,并通过采用数据统计回归分析的方法总结出HRB500钢筋与混凝土机械锚固粘结强度的计算公式,为我国现行混凝土结构设计规范的修订提供参考依据.
Through pull-out tests on the 45 samples,the influence factors of HRB500 steel bars mechanical anchoring per-formance which included concrete strength,concrete cover thickness,diameter of steel,steel bar anchorage length and transverse reinforcement ratio were studied.By using data statistical regression analysis method,the formula of HRB500 steel bars mechanical anchoring Bond Strength which could be used as reference to revise the design of concrete structures was concluded.
