Dear members,

I'm looking for those two articles:

Behavior and Ductility of Reinforced Concrete Short Columns using Global Truss Model in Concrete Beams

Abstract:

The main results of an experimental program on eight full-scale reinforced concrete short columns are presented. The specimens were subjected to compression and cyclic reversed uniaxial shear displacements. The parameters investigated were the value of shear ratio, the ratios of longitudinal and transverse reinforcement, and the normalized axial force ratio. Two different layouts of main reinforcement were tested: conventional (longitudinal) and a combination of longitudinal and bidiagonal reinforcement. Columns with shear ratio equal to 1 were shown to behave in a particularly brittle manner. The presence of bidiagonal reinforcement improved to some extent the ductility of the specimens, but not to the level required by current aseismic design. The relative performance of the specimens tested is evaluated according to various ductility criteria. A model for designing short columns is also presented.

Keywords: columns; cracking; reinforcement; shear; steel; strain

Modeling Error of Strength of Short Reinforced Concrete Columns

Abstract:

Probabilistic analyses of the modeling errors of several selected strength prediction models for short reinforced concrete (RC) columns are carried out. The selected strength models include the rectangular stress block model and the stress-strain relation-based theoretical model. A relatively large amount of test data on RC columns is collected from the literature, and the test results are com-pared with the predicted ones obtained from different strength mod-els. Both normal- and high-strength concrete columns are included in this study. The dependency of the modeling errors on concrete compressive strength and the load eccentricity is investigated. Probabilistic analyses of the modeling errors are carried out by using the pseudolikelihood estimation method. Sets of probabilistic models of the modeling errors by considering different analysis approaches are suggested for short RC columns.

Keywords: column capacity; column tests, modeling error; probabilistic analysis; reinforced concrete; reliability; short columns.
