This paper presents an nonlinear analysis to investigate the high strength concrete through the comparison with the concrete filled steel tubes and concrete filled GFRP. As a result, the high strength concrete has higher strength than the normal strength concrete filled CFGFRP that is widely used for the compressive strut member of the PSC Box Girder bridge. Therefore, it is confirmed that the high strength concrete is appropriate for the compressive struts of the PSC Box Girder Bridge.
