Abstract:
Traditional semiprobabilistic design of structures in buckling makes insufficient allowance for the probabilistic nature of their bearing capacity. The proposed approach takes into account the variability of concrete strength over the structure height, of its mean value in the structure population, of the end eccentricities, and finally of the strength of the reinforcement steel. Comparison of different concrete grades, reinforcement ratios, and slenderness ratios shows a substantial spread in reliability of the resulting structures. Significant improvement of the design methodology may be achieved by recourse to reliability analysis.
