Behaviour of Plate Anchorage in Plate-Reinforced Composite Coupling Beams
نویسندگان
چکیده
As a new alternative design, plate-reinforced composite (PRC) coupling beam achieves enhanced strength and ductility by embedding a vertical steel plate into a conventionally reinforced concrete (RC) coupling beam. Based on a nonlinear finite element model developed in the authors' previous study, a parametric study presented in this paper has been carried out to investigate the influence of several key parameters on the overall performance of PRC coupling beams. The effects of steel plate geometry, span-to-depth ratio of beams, and steel reinforcement ratios at beam spans and in wall regions are quantified. It is found that the anchorage length of the steel plate is primarily controlled by the span-to-depth ratio of the beam. Based on the numerical results, a design curve is proposed for determining the anchorage length of the steel plate. The load-carrying capacity of short PRC coupling beams with high steel ratio is found to be controlled by the steel ratio of wall piers. The maximum shear stress of PRC coupling beams should be limited to 15 MPa.

Experimental and numerical analysis of end anchored steel plate and CFRP laminate flexurally strengthened reinforced concrete (r. c.) beams
End anchors have been shown to significantly reduce premature plate end debonding failure of plate bonded strengthened reinforced concrete (r. c.) beams. One of the main interest in designing end anchors is to determine the minimum or optimal length of end anchors for a given thickness and height of the end anchor. This paper presents experimental and numerical studies in determining those opti...
