| 中文摘要 | 抗震设防标准的提高使钢筋混凝土桥梁柱配筋复杂,施工难度增大,一种曲线形夹式钢筋可用于代替柱的中间复合箍筋,使钢筋绑扎简化。文中介绍了这种夹式钢筋的构造与替代方法,给出了夹式钢筋等效置换中间复合箍筋的计算方法,进行了钢筋混凝土柱的试验研究。在绑扎柱钢筋时,对现有的复合箍筋配筋方式的柱和用夹式钢筋代替复合箍筋的柱,进行了钢筋绑扎比较,表明采用夹式钢筋,能够保证钢筋位置的准确,施工简便,显著地提高了施工效率。低周反复荷载试验结果表明,夹式钢筋置换复合箍筋后增强了构件的耗能能力,改善了构件的抗震性能。; It becomes difficult to assemble reinforcement bars due to the requirement in recent years for higher-density reinforcement to improve seismic design standard.The curved clip reinforcement is introduced as replacement of stirrups in reinforced concrete columns aimed to simplify working process.The calculation method of replacement ratio of clip reinforcement is given.The experiments of the reinforced concrete columns with conventional reinforcement and the clip reinforcement replaced stirrups are carried out.The process of assembling stirrup and clip reinforcement is recorded in manufacturing the specimens.It is easy to make sure the correct position of steel bars in the reinforcement framework, simplify the execution procedure and lead to improve the efficiency.The lowcycle reversed loading test is carried out and the results show that the columns that replaced a conventional reinforcement bar with clip reinforcement have the equivalent bearing capacity and higher energy dissipation ability compared with that of conventional reinforcement. |
