ABSTRACT
The bending stiffness of joints is a critical factor that impacts the bearing capacity of large-span spatial reticulated shell structures. To address the issue of relatively low bending stiffness of traditional socket joints, a novel type of sprayer joint is introduced in this study. Initially, the bending performance of the socket joint is validated, leading to the proposal of the sprayer joint. Then, a refined finite element model is established to investigate the bending performance of the sprayer joints with varying surrounding bolt radii under axial tension and compression loads. Subsequently, an improved bilinear model is developed to effectively determine the bending performance with precise yield position. Finally, the comparative performance of the new sprayer joint and the traditional socket joint in single-layer cylindrical reticulated shells is studied in detail. The findings indicate that the bending performance of the new sprayer joint surpasses that of the traditional socket joint, and the ultimate load of the new sprayer joint reticulated shell has significantly increased compared to the traditional socket joint, highlighting the efficiency and success of the new sprayer joint design. Moreover, it is observed that axial compression and the radius of surrounding bolts can enhance the bending performance, while axial tension exhibits opposite effect. The failure mode of the new sprayer joint is elucidated, and the improved bilinear model accurately describes the yield position and bending process of the joint. These conclusions offer valuable insights for the structural design and application of the sprayer joint.
