Reliability Bases for High-Strength Concrete Columns
Publication: Journal of Structural Engineering
Volume 123, Issue 10
Abstract
High-strength concrete (HSC) has found its main application in the lower columns of high-rise buildings. Due to its large application, type of failure, and importance to structural integrity, the reliability assessment of HSC columns is an extremely important issue. On the other hand, this assessment is a very involved issue. First, a unique formulation of the failure criterion has not yet been established. Second, the moment magnification method, when applied to slender HSC columns, may produce conservative or unconservative estimates of the load effects depending on the load eccentricity. Third, information on the resistance variability of HSC columns is scarce. In this paper, the basic requirements for reliability analysis of HSC columns are presented. A failure criterion is sought, a procedure that does not resort to the moment magnification method is established for the computation of the load effects on slender columns, and probabilistic descriptors of load and resistance of HSC are investigated.
