摘要:
为了研究化学锚栓能否用于地震地区和受拉区混凝土构件，对化学锚栓加固植筋混凝土构件的锚固性能进行了试验。通过拟静力试验，研究了锚固构件的破坏形态、锚栓在反复荷载作用下的锚固效果和抗震性能。试验结果表明：化学锚栓的动载锚固效果良好，可以用于地震地区和受拉区混凝土构件的锚固；化学锚栓提高了构件的承载力和延性，尤其在反复荷载试验后期，在限制构件承载力下降和位移增大方面起到了重要作用；锚栓施工技术是影响构件抗震性能的重要因素。
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.
