Based on experimental research, the failure modes of adhesive anchorage system resist to pullout load are discussed. The failure of adhesive anchorage system can be derived from 5 factors: concrete failure, steel failure, adhesive failure, adhesives and concrete interface failure as well as steel and adhesive interface failure. Based on the features of different media in adhesive anchorage system, such as concrete, steel bar, adhesives, and bond-slide relationships between them, a finite element model for the analysis of multi-media system is proposed. A computer program is developed, whose result shows taht the calculated result coincides well with the test result.
