摘要:
建立了无机胶植筋极限状态方程,分别对植筋试件的粘接锚固强度、钢筋屈服强度、混凝土强度、几何尺寸、计算模式的准确性等大量试验数据进行了统计分析,确定了可靠性指标.采用一次二阶矩法(FOSM)对无机胶植筋进行了可靠度分析,分析结果表明:钢筋直径越大、混凝土强度越低,无机胶植筋所需的粘接锚固长度越长.基于以上的分析,提出了基于可靠度理论的无机胶植筋的锚固长度计算方法,计算结果与试验结果对比表明,该锚固长度计算方法可以用于混凝土植筋的设计计算.
Abstract:
At first, this paper established the limit state equation of inorganic glue bonded rebars, and conducted respectively statistical analyses of a large number of experimental data of the anchoring strength, steel yield strength, concrete strength, geometry size and the accuracy of the calculation model, by which the reliability index is determined. Then the central point law in first order second moment method (FOSM) was adopted to analyze the reliability of bonded rebars with inorganic material. The analysis results showed that the greater reinforcement diameter was, the lower concrete strength was and the longer anchorage length was. Finally, the adhesive anchorage design method of bonded rebars with inorganic material was based on reliability theory. By means of comparing the calculation results with experimental results, it can be concluded that the calculation methods of anchorage length can be applied to the calculation and designing of concrete bonded rebars.
