“…The results showed that the sleeve structures have good static performance and hysteretic behaviors. Zhang et al [22] applied the simplified theory to analyze the sleeve structure and pointed out the factors affecting the contact between the core and the sleeve, and parametric studies were performed to investigate the effects of the factors on the improvement of the ultimate bearing capacities of the sleeve structures. A parametric study was conducted to quantify how essential factors, including the core protrusion length above the sleeve-stiffness ratio of the core-to-sleeve core-slenderness ratio and gap between the core and sleeve affect the mechanical behaviors of the sleeve structures [23].…”

Long-span prestressed double-layer composite torsional reticulated shells have beautiful shapes, which make them a solution widely applied in public buildings requiring long-span structures, such as airports and stadiums. However, once the progressive collapse occurs, this will cause serious issues. There are few studies on the damage assessment of long-span spatial structures under accidental loads. This paper proposes a new dynamic damage evaluation index that takes into account the displacement and the cumulative plastic energy dissipation to evaluate the damage of the long-span prestressed double-layer composite torsional reticulated shell. Sleeve structures were applied to the long-span space structures to study their control effect on structural damage. The equivalent load transient unloading method was used to analyze the dynamic time history of the structure. Results show that the structure suffered severe damage and progressive collapse failure after removing four nodes at different positions near the supports. In the position where the plastic hinges first appear and the position with the maximum displacement, the sleeve structures have a poor damage control effect on the structure. Arranging the two sleeve structures in the position of maximum stress, the damage of the structure can be controlled, thus reducing the severe damage and progressive collapse failure to basic intact damage.
