| Abstract: | The variation regularity of the concrete structural reliability of the axial forced component and the bending component was studied with different types of the resistance varied with time. It is shown that the start point of the deterioration of the resistance is a key factor for the structural reliability. The influence of non bearing elements on it, such as the concrete cover, the concrete strength, the carbonization speed and the design period, is analyzed. |
