摘　　要：渡槽支架是渡槽结构中的重要组成部分。其抗震性能直接关系到渡槽结构的抗震能力。通过3个C50级高强混凝土渡槽支架模型试件在低周反复荷载作用下的抗震性能试验，从试验现象、结构破坏特征、滞回曲线、骨架曲线以及结构延性系数等几个方面探讨了高强混凝上渡槽支架的抗震性能。结果表明，在试验条件下，高强混凝土支架具有较好的抗震性能，结构延性能够满足工程扶震要求。The adqueduct bentframe is main component of the adqueduct structure. The aseismatic behavior of bentframe is directly connected to the aseismatic ability of adqueduct structure. Based on an experiment of three specimens of C50 high strength concrete bentframemodels suffering from horizontal cyclic load, this paper deals with the aseismatic behavior of the high strength concrete adqueduct benframe from several aspects which are experimental phenomena, failure characteristic, hysteresis curve and ductility coeffcent. The results show that adqueduct bentframe made of high strength concrete has a good aseismatic performance and the stfucture ductility meets the aseismatic requirements of engineering on the given condition of this experiment.
