These days structures with ultra high strength concrete and steel are increasing because of the rising demands for high-rise buildings and long span bridges. The techniques of high strength material has been developed rapidly, as they have a lot of benefits such as the reduction of the amount.
In this paper, we performed the basic research of practical application examples of the bridge and the structural characteristics of ultra-high-strength concrete and steel strand.
