Influence Analysis of Joint's Stiffness on Spatial Reticulated Shell
Joint’s stiffness has important influence on the stability behavior of large-span spatial reticulated shell. In this paper, the nonlinear beam-column element with end springs is taken as the analysis model of members of single-layer reticulated shell, the whole process of nonlinear stability for single-layer reticulated shell is analyzed with the software ANSYS, the influence of joint’s stiffness on the stability of single-layer reticulated shell is studied. Some important conclusions were obtained, which can provide theoretical foundation for the stability ultimate bearing capacity analysis of large-span spatial reticulated shell considering joint’s stiffness and can be applied on practical design.
