The　application　of　large-span　spatial　structures　has　become　increasingly　widespread　in　the　construction　industry;　however,　relevant　research　on　fire　resistance　remains　limited.　Thus,　it　is　crucial　to　develop　assessment　methods　and　temperature　distribution　prediction　models　tailored　to　the　high-temperature　fire　behavior　of　large-span　spatial　structures.　This　study　provides　a　comprehensive　review　of　recent　research　on　the　mechanical　properties　and　analytical　methods　for　cable　members,　key　joints,　and　the　overall　structure　under　fire.　Additionally,　it　discusses　current　gaps　and　outlines　future　research　directions　to　advance　fire　protection　design　for　large-span　spatial　structures.　The　primary　research　directions　include:　In　terms　of　members　and　key　joints,　develop　a　standardized　high-temperature　performance　degradation　model　for　cable　members　and　key　joints　in　large-span　spatial　structures.　Regarding　the　overall　structure:　utilize　advanced　numerical　simulations　and　theoretical　derivations　to　establish　methods　for　assessing　fire　response　behavior　and　predicting　temperature　field　distribution　in　large-span　spatial　structures.　Effectively　implement　fire　protection　design　methods　tailored　for　large-span　spatial　structures　in　practical　construction　projects.
