Reliability analysis of slender columns using the general method with linear creep theory

Abstract To analyze the reliability of slender columns subjected to axial force and uniaxial bending moment, with a slenderness index between 100 140, 216 were modeled. The square cross-section was adopted, three different configurations for longitudinal reinforcement. In calculation, general method linear creep theory applied. Several factors varied: index, reinforcement ratio, steel bars arrangement, compressive strength concrete, first-order relative eccentricity. For analysis purposes, Monte Carlo followed by First Order Reliability Method (FORM). Considering results obtained, it observed that is usually higher lower ratios varies according configuration cross-section.
