Abstract: To get the bearing behaviors of the curved girders, three model experiments were carried out under tensile force by way of a single jack.The load-displacement curve, out-plane displacement were measured, as well as the strain at the concerning positions.Target curves and expected failure mode of the experiment components were obtained.Finite element models were established.The bearing behaviors of the curved girders were simulated and the results of experiments and FEM were compared.By different types of out-plane supporters, different effects were obtained.The effects of different initial defects applied on the models were analyzed as well.The results show that the experiment results and FEM results agree well, and the design is reasonable and safe.
