Application of ultra-high performance concrete to pedestrian cable-stayed bridges

The use of ultra-high performance concrete (uhpc),which enables reducing the cross sectional dimension of the structures due to its high strength,is expected in the construction of the super-long span bridges. unlike conventional concrete,uhpc experiences less variation of material properties such as creep and drying shrinkage and can reduce uncertainties in predicting time-dependent behavior over the long term. this study describes uhpc's material characteristics and benefits when applied to super-long span bridges. a uhpc girder pedestrian cable-stayed bridge was designed and successfully constructed. the uhpc reduced the deflections in both the short and long term. the cost analysis demonstrates a highly competitive price for uhpc. this study indicates that uhpc has a strong potential for application in the super-long span bridges. © school of engineering,taylor's university.
