STRENGTH ANALYSIS OF RETROFITTED RC COUPLING BEAM WITH BOLTED SIDE STEEL PLATES
Experimental studies show that composite beams using bolts to attach steel plates to the side faces of existing reinforced concrete (RC) coupling beams can enhance both of their strength and deformability. The behavior of those composite beams differs substantially from the behavior of typical composite beams made up of steel beams and concrete slabs which only involve longitudinal slip whereas the former are subjected to both longitudinal, vertical and rotational slips. In this study,mixed analysis method was firstly adopted to develop the fundamental equations for accurate prediction of the strength of steel plate retrofired RC coupling beams. The strength of the retrofitted coupling beams derived, has considered vertical and longitudinal slips of the steel plates as well as the demand of shear strength of anchor-bolt connection group. The strength analyses are validated by the available experimental results which were conducted by authors and the strength of the specimens predicted from the theoretical model is found to be in good agreement with that from the experimental results.
