“…For example, the structure of the roof of the ice-skating rink in Bad Reichenhall, Germany collapsed due to blizzard attack (Dietsch et al [36]). In addition, Takahashi et al [33] analyzed the reliability of the steel roof members under snow disaster and found that the reliability level of such members designed according to the Japanese building code is low.…”

“…ultimate capacity of beam string structures under full-span load and half-span load combination, strength of reinforced concrete columns under vertical load and horizontal load combination), and thus the random properties of load ratio have a significant impact on the bearing capacity (see [31][32]). It is reported that the adverse effect on bearing capacity caused by non-uniform snow load may lead to low safety of the BSS designed according to the current load partial factors (see Takahashi et al [33]). The previous experimental and theoretical studies mainly focus on the mechanical performance of BSS under the fixed load ratio criterion, while the research on the reliability of BSS under random load ratio is seldom.…”

“…Several meta-model techniques were applied to address the problem of lack of on-site weather information, and different studies regarding meteorological data were conducted in the last few years [24][25][26][27]. One of the most widely used techniques is kriging [26,28,29].…”

“…This highlights the importance of stability research of such structures [1][2][3][4][5][6][7][8][9][10]. The growing frequency of heavy snowstorms around the world has increased the urgency of stability research of space structure under snow load [11][12][13][14][15][16][17][18][19].…”

The snow load distribution has a significant impact on the stability of single-layer reticulated shells, a conventional type of long-span space structure. This paper attempts to disclose how the snow load distribution influences the stability of two types of single-layer reticulated shells, namely, spherical reticulated shell and cylindrical reticulated shell. Two influencing factors were taken into account: the asymmetry of snow area on the projection surface of the shell, and the non-uniformity of snow thickness along the radial direction of the shell. The nonlinear finite-element program ANSYS was adopted to calculate the bearing capacities of the two shells under different snow load distributions, in the light of the equilibrium path under each distribution, and to identify the most dangerous distribution of snow load for each shell. The results show that: the asymmetry and non-uniformity have obvious impacts on the stability of spherical reticulated shell, and even greater impacts on that of cylindrical reticulated shell; the most dangerous snow load distributions for spherical reticulated shell and cylindrical reticulated shell are the non-uniform distribution across the half span of the two outermost rings, and the non-uniform distribution across the half span in the middle, respectively. The research results provide reference for keeping large public buildings safe under snow load.
