主 题:CFRP reinforced beam Interfacial interaction Smart CFRP-FBG plate Deflection Experimental investigation
摘 要:Many beam structures suffer from gradual performance degradation with the increase of service *** recover the bearing capacity of these beams,carbon fiber reinforced polymer(CFRP)plates are developed to attached on the beam *** check the structural performance of the CFRP reinforced beams,smart CFRP plate with FBGs in series is designed and LVDTs are adopted to measure the *** deflection of the reinforced beam is given based on the elastic conversion cross-section *** experimental results validate the effectiveness of the proposed *** study shows that the CFRP reinforced zone has a larger flexural rigidity than the pure steel beam *** general distribution of the deflection along the span of the CFRP reinforced beam can be described by the proposed *** provides a scientific design guidance for the deflection control of CFRP reinforced structures.
