摘要
对梁端负弯矩采用植筋加固后的框架节点进行了抗震性能试验研究。共设计制作了5个试件,其中1个试件为对比试件,其他试件为增大截面法加固构件,加固试件中1个为新增钢筋贯穿节点区且无粘结,3个试件采用化学植筋。通过试验研究了不同锚固方式、不同锚固深度对节点受力性能的影响,同时也研究了反复荷载作用下植筋的抗震性能。
The seismic performance of the frame joints and anchorage seismic performance with beam Strengthened by bonded rebars are studied. Five specimens are designed, one contrastive specimen and four reinforcement specimens using increasing section method, which including one specimen that the anchorage reinforced through the frame node without adhesive and three chemical anchorage reinforcement specimens. The impacts about the node force performance reinforced in different angles and different length are analyzed, and the rebars seismic performances under the cyclic loads are concluded.
