Strengthening steel bridges with new high modulus CFRP materials

چکیده
This paper presents the details and relevant findings of an experimental program which was conducted in three phases to investigate the behavior of steel-concrete composite bridge girders strengthened with new high modulus carbon fiber reinforced polymer (HM CFRP) materials. In the first phase, the feasibility of various lIM CFRP strengthening systems was examined. The second phase investigated the behavior of the strengthened beams under overloading conditions. The fatigue durability of the strengthening system was investigated in the third phase. Based on the findings of the experimental program, simplified design guidelines are presented for the design and analysis of steel-concrete composite bridge girders strengthened with lIM CFRP materials.
