摘要：

In this paper, the numerical simulation method was used for the simulation of expansion and 3-point bending in a fiberglass-reinforced plastics (FRP) reinforced concrete beam interior crack. The failure modes and the ultimate baring capacity which are under a concentrated load, as well as the influence of concrete beam notch height (a 0) and FRP length (L x) for the failure mode and ultimate bearing capacity were discussed. Furthermore, the influence of the mechanical properties of FRP on load capacities and acoustic emission (AE) was numerically investigated. The numerical simulation result shows the load-displacement and the AE-displacement curves; the minimum principal stress patterns of the breaking process of concrete beam are also given. The simulation results agree well with the experimental observations. Numerical modeling results show that the numerical simulation method provides a new analysis tool for studies on mechanical behavior and failure mechanisms of concrete structures.
