Direct evaluation of the buckling loads of semi-rigidly jointed single-layer latticed domes under symmetric loading
AbstractThe analysis of tubular single layer structures involves geometric nonlinear methods that can consider large displacements of nodes. In addition, the analysis of single-layer structures must take into account not just member buckling, but also local and overall buckling situations. Collapse is strongly influenced by both geometric parameters and joint rigidity. Even though current computing power does allow designers to run nonlinear analyses as many times as needed, efficiency of the design process is based on the designer’s ability to define an initial design close enough to the final geometry of the structure. This paper presents results obtained from analysis of the nonlinear behaviour of single-layer domes with different geometric parameters and joint rigidity. The study is performed for two load cases and concludes with the proposal of a new formula which allows designers a rapid estimation of buckling loads for semi-rigid jointed single-layer latticed domes under symmetric loading conditions.
