摘　　要：通过对钢筋与金属套筒之间采用植筋胶粘结的拉伸抗剪试验,探讨了植筋胶的粘结机理和拉伸抗剪破坏模式。在对试验结果综合分析的基础上,提出了植筋胶拉伸抗剪粘结滑移本构关系的三段式模型,为植筋锚固有限元分析提供了必要的基础。Through pullout tests for shear resistance of the adhesive steel bar in the metal tube, the bond principals and failure modes of adhesives are studied. Based on test results, a three-stage formulation for bonding shear stress-slip relationship between the adhesive bar and the tube was developed, which is fundamental work in finite-element analysis of adhesive reinforcement in further studies.
