| Abstract: | The formations, structural characteristics and styles were proposed for a particular new kind of partial double layer spherical reticulated domes (PDLSRD), which is the central single layer and peripheral double layer reticulated spherical dome. This paper focuses on the buckling analysis for Kiewitt spherical lattice domes. The effects of single layer scope on buckling loads were investigated. And the stability performances of the domes with central single layer only and opens were also analyzed, respectively. Furthermore, the detailed comparison analysis were performed to seek the inherently buckling rules for both analytical model variations and support stiffness. |
