Abstract：

The　study　analyzed　and　compared　the　effects　of　thermal–fluid–solid　coupling　dynamic　boundary　conditions　and　traditional　fixed-boundary　conditions　on　the　distribution　of　the　temperature　field　under　fires.　The　feasibility　of　simulating　the　temperature　field　distribution　was　confirmed　by　using　thermal–fluid–solid　coupling　dynamic　boundary　conditions.　Then,　the　traditional　temperature　field　analysis　methods　were　corrected　by　including　a　flow-based　heat　exchange　coefficient,　and　the　feasibility　of　this　approach　was　also　confirmed.　The　fire　temperature　field　in　a　rectangular　air-supported　membrane　structure　was　analyzed　through　parameterization.　The　fire　temperature　field　model　of　the　air-supported　membrane　structure　was　established　using　temperature　field　data　fitting.　Furthermore,　the　study　explored　the　high-temperature　material　properties　of　P-type　membranes　and　analyzed　and　compared　the　temperature　field　of　the　air-supported　membrane　structure　with　time-varying　mechanical　properties　of　the　membrane　material　to　that　without　time-varying　properties.　©　2024　Elsevier　Ltd
