The　cable-supported　barrel　vault　(CSBV)　structure　system　is　a　new　type　of　hybrid　spatial　steel　structure　based　on　a　beam　string　structure　(or　truss　string　structure),　suspendomes,　and　cylindrical　lattice　shells.　Steel　cables　(e.g.,　steel　wire　rope　cables,　steel　strand　cables,　semiparallel　steel　tendons,　and　steel　rods)　are　key　components　of　CSBV　structures.　However,　they　have　different　elastic　moduli　and　thermal　expansion　coefficients.　In　this　study,　the　roof　of　a　textile　workshop　(the　first　CSBV　structure　in　China)　was　analyzed　with　four　types　of　cables　under　the　effect　of　varying　temperature.　Under　half-span　loading　and　full-span　loading,　the　structural　internal　force　and　displacement　at　varying　temperatures　were　obtained　from　finite　element　models　employing　four　different　types　of　steel　cables.　The　internal　force,　displacement,　and　horizontal　arch　thrust　changed　linearly　with　increasing　temperature.　Moreover,　the　dynamic　characteristics　of　CSBV　with　varying　temperature　were　analyzed.　The　frequency　of　the　CSBV　changed　linearly　with　increasing　temperature.　Based　on　the　dynamic　characteristics　of　CSBV　with　varying　temperature,　a　seismic　response　time-history　analysis　was　performed.　The　variation　in　the　maximum　responses　of　the　internal　force,　displacement,　and　horizontal　arch　thrust　was　obtained.　In　each　case,　the　mechanical　behavior　of　the　CSBV　with　semiparallel　steel　tendon　cables　was　strongly　affected　by　the　temperature.　Therefore,　semiparallel　steel　tendons　are　not　recommended　as　components　of　CSBV　in　cases　where　large　temperature　changes　can　be　expected.　Thereafter,　a　scale　model　of　a　CSBV　was　designed　and　used　for　experiments　and　corresponding　finite　element　analyses　under　varying　temperature.　Experimental　results　show　that　the　finite　element　method　is　effective　for　analyzing　the　mechanical　behavior　of　CSBV　under　varying　temperature.
