Development of Seismically Damage-free Bridge Columns using Ultra High Strength Fiber Reinforced Cement

本研究的目的是开发一种新的延性无损伤桥梁柱，使用超高强度纤维增强水泥复合材料，而不是提供高侧向约束的核心混凝土的拉杆。通过低周反复荷载试验、复合荷载试验和非线性动力响应分析，发现超高强度纤维增强水泥基复合材料可以开发出一种新型的延性无损伤桥梁柱

This investigation aimed of developing a new ductile damage-free bridge columns using ultra-high strength fiber reinforced cement composite in stead of providing high lateral confinement to the core concrete by ties. Based on cyclic and hybrid loading experiments as well as nonlinear dynamic response analysis, it was found that a new ductile damage-free bridge column can be developed using ultra-high strength fiber reinforced cement composite
