Abstract

In order to precisely analyze the mechanical performance of chemical anchorage, a new method using cohesive zone model to simulate the bond layer between reinforcement and concrete interface has been put forward. The three-dimensional model of ABAQUS constructed was based on chemical anchorage. In this model, the cohesive zone model with a certain thickness was used for bonding interface, the constitutive relation of which fell on the bilinear stress-opening displacement model. The influence of parameters on the load-displacement curves of single steel drawing was analyzed. The conclusion indicated that the ultimate bearing capacity of the structure (the maximum load of the load-end) was mainly determined by the fracture strength. The bearing capacity increases with higher fracture strength, and the fracture toughness has little influence on the ultimate bearing capacity of anchorage.
