Corrosion on the node or support of the spatial grid structure in cement production lines can easily lead to the failure of the related rods, causing the continuous collapse of the spatial grid buildings(structures). Finite element numerical simulation is used to study the continuous collapse resistance of structures in service under different corroded years. In the dynamic response process, the maximum stress of single-layer reticulated shell reaches 1.5 times of that under static action, some members yield, and the displacement of adjacent joints reaches 1/500 to 1/300 of structural span. The double-layer spherical reticulated shell structure has higher redundancy and better resistance to continuous collapse.
