EXPERIMENTAL RESEARCH ON MODEL OF CFRP TIED BOXED STEEL ARCH BRIDGE
Carbon Fiber Reinforced Polymer can be used as suspender in boxed steel arch bridge which is of good physical and mechanical performance. A type of thread anchorage for CFRP has already developed and its adjustably telescopic range is 10 cm that is used for any diameter below 10 mm. According to the similarity principle,a scale model for CFRP tied arch bridge has made in this paper. Meanwhile,stress and deformation performances about the model have been analysised respectively. During applying concentrated force and distributed force at the mid-span,the tensile force for suspender is large because of its vertical deformation and its results are coincide with the one of model analysis,at the same time,A compressive stress for the relative steel boxed sections is big. Test results show that the stress and deformation performance for CFRP steel boxed arch bridge are well. It can be applied for the similar bridges for CFRP suspender.
