Abstract:
Seismic behavior of plate-reinforced composite (PRC) coupling beams was simulated based on the finite element software, and the calculated results were compared with those of the experiments to ensure the correcteness of the simulation model.Furthermore,with abundant simulations, span-to-depth ratio, plate anchorage length in the wall region, plate thickness, longitudinal reinforcement ratio of beam and wall reinforcement ratio were all considered to analyse the effect on seismic behavior of PRC coupling beams.The results show that the tension softening property of concrete was simulated based on the relationship between stress and fracture energy, and the elastic-plasticity finite element analysis of the model was better conducted. The effects of changes of span-to-depth ratios on yield loads and peak loads of the coupling beams are significant. The yield loads and peak loads of PRC coupling beams gradually decrease with the increase of span-to-depth ratios, but?their ductility performance is gradually improved. The load bearing capacity and stiffness of the coupling beams increase with the plate anchorage lengths, plate thicknesses and longitudinal reinforcement ratios, but the effects diminish as the span-to-depth ratios of coupling beams decrease. The load bearing capacity of the coupling beams increase with the increaseing wall reinforcement ratios, but the effects diminish as the wall reinforcement ratios increase
