Abstract: An application of concrete members of annular cross sections reinforced by steel bars uniformly distributed throughout their perimeters to building columns, bridge piers, carriers of overhead power transmission lines and their design methods are discussed. The modelling of resisting compressive forces and bending moments of eccentrically loaded cross sections as particular members of tubular members and their statistical parameters are presented. The second order effects of columns, piers and poles caused by their structural deformations are analysed. The time-dependent margins of particular members exposed to extreme loading situations due to floor and climate extraordinary actions are considered. The instantaneous survival probability of particular members and its application features in probability-based design of columns, piers and poles are developed. The long-term survival probability and reliability index design of particular and structural members are based on the unsophisticated method of transformed conditional probabilities. The analysis of revised reliability indices for structures subjected to fixed values of abnormal extraordinary actions is based on Bayesian approach.
