Stress distribution and delivery of anchored rebar, deformation and displacement of connected plates, stress distribution of the bolts, distribution and expansion of concrete cracks in segment and the final failure mode were investigated under different load conditions. The results show that the stress of anchored rebar decreases with the increasing distance of joints between anchored rebar and embedded parts. Whilst the transfer curve presents a trend of slowness after steepness. The whole rigidity of joint is enhanced and bearing capacity of structure is improved, resulting from the existence of anchored plates and anchored rebars of embedded parts. The final failure mode of the structure refers to the fracture occurring in joints of anchored rebar and embedded parts, and the whole embedded parts create buckling deformation. Hence, it is available to increase the connected performance of embedded parts as well as anchored rebar and correspondingly strengthen the rigidity of embedded plates to improve the overall performance of the structure. %U http://zgglxb.chd.edu.cn/EN/abstract/article_2598.shtml
