The resistance of new type of hollow concrete-filled circular steel tubular members under axial compression is considered. The effect of interaction between steel tube and spun concrete core contact surfaces on composite member compressive strength is analysed. The experimental values of member’s resistance and its mechanical model uncertainty are presented. The necessity to assess the structural safety of precast members exposed to actions in pre-use and use working lives is discussed. Peculiarities of the mechanical model describing the safety margin of ageing and not ageing compression members are analysed. The probability-based assessment of structural safety of particular members (compressive cross-sections) subjected to extreme loadings is presented and illustrated by numerical example.
