Nov 15, 2017  A total of 18 high strength concrete columns confined by spiral reinforcement were tested under concentric compression. The confined concrete circular specimens were produced using 4 longitudinal reinforcements (18 mm dia.).In these specimens spiral reinforcements had a diameter of 8 mm and were spaced at 55 mm, 80 mm, 110 mm, 160 mm.The specimens index from 1 to 4 are for 4

Jul 07, 2005  The behavior of high strength concrete columns is characterized by the sudden spalling of concrete cover, leading to a loss of axial capacity. A comparative study of existing confinement models of high strength concrete columns was also conducted to assess their capabilities of predicting the actual test behavior.

FLEXURAL BEHAVIOR OF HIGH-STRENGTH RC COLUMNS

The proposed stress-strain curve model is applied to predict the flexural behavior of the plastic hinge regions of the columns under axial load and bending moment with moment gradient (shear) at the second phase of the investigation. The emphasis is placed on estimation of the flexural strength of columns made of high-strength concrete.
