Design Method for Stability of Single-Layer Reticulated Shells with Semi-Rigid Joints
Using nonlinear beam element (beam 189 element) with end spring elements (combin39) in the software ANSYS,K8 and K6 single-layer reticulated domes with bolt-joint joints were analyzed based on several different parameters including bending stiffness,ratio of rise to span,rotational stiffness,ball size,asymmetric load distribution,tube section,support condition and initial imperfection,and key parameters having influence on the load carrying capacity of a dome were thus identified. And so,a formula was established for the estimation of buckling loads for a semi-rigidly jointed single-layer latticed dome.
