THE INFLUENCE OF JOINTS STIFFNESS ON STABILITY OF RETICULATED SHELL

摘要：

Joints stiffness has important influence on the stability ultimate bearing capacity 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 spatial reticulated shell,the whole process of non-linear stability for single-layer reticulated shell is analyzed with the soft ANSYS,the influence of joints 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 joints stiffness and can be applied on practical design.
