Abstract
The large - span single - layer reticulated shell structure is a structure sensitive to the load distribution. Different distribution of snow load has an effect on the stable bearing capacity of the reticulated shell structure. The unfavorable snow load distribution may cause the stable bearing capacity of the reticulated shell to decrease greatly. In this paper, a single oblique rod type reticulated shell structure is taken as an example. According to the characteristics of the reticulated shells, eight stripes are divided into a lattice size in the longitudinal direction and span direction, and the snow load distribution is classified according to the permutation and combination. The stability of the reticulated shell structure is determined by the arc-length method, taking into account the sensitivity of the snow load in the longitudinal direction and the span direction. The results show that the maximum sensitivity coefficient of the stability of the reticulated shells with snow loads is 0.083 and 0.404, respectively, along the longitudinal length and the span direction. Compared with the sensitivity coefficient of the snow load distribution position along the longitudinal length direction and the span direction, the most sensitive snow load distribution position of the reticulated shell structure is obtained from the 4th to 8th rows.
