The　finite　element　software　ABAQUS　is　used　to　calculate　the　deformation　of　reinforced　concrete　walls　under　fire.　The　calculated　results　agree　well　with　previous　experimental　results.　Based　on　the　finite　element　model,　the　influences　of　such　parameters　as　axial　load　level,　lateral　load　level,　height-to-thickness　ratio,　wall　thickness,　concrete　compressive　strength,　steel　reinforcement　yield　strength,　steel　reinforcement　ratio　and　concrete　protection　thickness　on　deformation　and　fire　resistance　of　walls　are　analyzed　systematically.　It　is　found　that,　under　the　conditions　of　big　axial　load　level　or　wall　thickness　without　lateral　load　and　small　height-to-thickness　ratio,　the　reverse　deflection　of　reinforced　concrete　walls　in　fire　is　apt　to　occur.　Within　the　work　range　of　parameters　in　common　use,　the　fire　resistance　of　walls　decreases　with　the　increase　of　axial　load　level,　lateral　load　level,　height-to-thickness　ratio,　steel　reinforcement　yield　strength　or　steel　reinforcement　ratio,　and　increases　with　the　increase　of　wall　thickness　or　concrete　compressive　strength.
