| Abstract: | In this present paper, the material properties of carbon fiber reinforced polymer (CFRP), which has been newly developed in civil engineering, is introduced, followed by a comparison with regular steel strand. The mechanical behavior of long span concrete arch bridge with CFRP hangers and tie bars is (analyzed) through examples. Results of the analysis demonstrate that CFRP is a promising material for applica?tion of the bridge. |
