| Abstract: | There are great differences in the mechanical behaviour of the RC members thathave different surfaces heated under fire.The present paper compares the behaviours,including section temperature field,deformation and ultimate load capacity, of RCeccentrical compression members with two surfaces heated and that with three surfacesheated.It illustrates the effect of different temperature fields on the behaviour of theRC members further and provides a basis for the theoretical analysis of a structure underhigh temperature. |

| Keywords: | high temperature reinforced concrete memer under flexure and axial load ultimate load |
