RODRIGUEZ-GUTIERREZ, J. A  y  ARISTIZABAL-OCHOA, J. D. Biaxial bending of slender HSC columns and tubes filled with concrete under short- and long-term loads: II) Verification. Ing. Investig. [online]. 2014, vol.34, n.3, pp.19-25. ISSN 0120-5609.  https://doi.org/10.15446/ing.investig.v34n3.42950.

An analytical method that calculates both the short- and long-term response of slender columns made of high-strength concrete (HSC) and of tubes filled with concrete with generalized end conditions that are subjected to transverse loads along the span and to axial loads at the ends (causing single- or double-curvature under uniaxial or biaxial bending) is presented in a companion paper. The columns that can be analyzed with this method include those with solid and hollow (rectangular, circular, oval, C-, T-, L-, or any arbitrary shape) cross sections and columns made of circular and rectangular steel tubes filled with HSC. In this paper, the validity of the proposed method is tested against experimental results from the technical literature that examined over seventy column specimens.
