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.
