Single layer reticular domes are structures which can effectively cover a large area without columns inside. However, it should be noticed that the dome structures are subjected to severe instabilities in both elastic and plastic behaviors. Thus the paper presents an efficient elasto-plastic formulation for single layer reticular domes with semi-rigid connections, and the buckling behavior of the domes is investigated under multiple loadings such as gravity loads and earthquake motions. Furthermore, a system for graphic presentation and analyses implemented in this study are briefly explained with a comment for a future work to be performed for further development.
