In this paper, 3D3S 14.1 is used for the structural calculation and analysis of a single-layer Kaiwitt-type spherical reticulated shell roof structure of a swimming pool, and the modal, internal force and displacement of the structure are analyzed respectively. The periods are 0.36s, 0.34s and 0.31s, respectively, and the most unfavorable mode shape is the top Z translation up and down. The maximum pressure of the reticulated shell structure rod is -129.5kN, the maximum negative displacement of the structure is -21.0mm, and the most unfavorable internal force and displacement occur at the support. The maximum stress ratio of structural members is 0.78, which can meet the calculation requirements of bearing capacity.
