- Abstract:
- In order to research whether the chemical anchor could be used in seismic area or tensile region of reinforced concrete (RC) members, the test on the anchor behavior of RC members confined by chemical anchor was carried out. Through quasi static test, the failure modes of RC members confined by chemical anchors, the effects of anchor and the seismic behavior were studied under cyclic load. The experiment results show that the dynamic anchor effectiveness of chemical anchor is good, and the anchor can be used in seismic area or tensile region of RC members. The bearing capacity and ductility of members are enhanced by the chemical anchor, especially in later period of cyclic load test, the chemical anchor plays an important role in preventing the decrease of bearing capacity and increase of displacement. The anchor construction technology is an important influence factor on the seismic behavior of members.
