Comparative Study on Drawing Characteristics of GFRP Reinforcement and Reinforcement
In this paper,the mechanical characteristics of pullout resistance of GFRP and steel anchors are investigated by pullout test and nu-merical simulation of GFRP anchors.The stress-strain curve characteristics,damage process,and anchorage characteristics of both are ana-lyzed comparatively.The results show that the stress-strain curves of GFRP bars are completely different from those of steel bars,and the strain of GFRP anchors is significantly smaller than that of steel bars when reaching the destructive load.The damage of GFRP bars is brittle,while that of steel bars is elastic-plastic.The difference in anchorage pullout characteristics between the two is obvious,the axial stress transfer depth of GFRP anchors is greater than that of steel bars,and the shear stress distribution of GFRP anchors is more uniform.The results of the study can provide a reference for its application and stability analysis in practical engineering.
