Experimental investigation of short steel columns with localized corrosion

Repair of corroded and buckled short steel columns using concrete-filled GFRP jackets

“…The columns consisted of W4 Â 13 (US designation) columns with different patterns of simulated corrosion. The columns were previously tested to evaluate the capacity of short steel columns with localized severe corrosion [11]. After testing, the columns were repaired with different configurations of concrete-filled GFRP jackets to investigate the effectiveness of this repair technique.…”

“…In the current study, the columns that were previously tested by Karagah et al [11] were put into four groups as summarized in Table 1. Specimens were grouped on the basis of similar simulated corrosion patterns, axial load-deflection response, failure modes, and residual loads at the conclusion of previous testing.…”

“…The initial out-of-straightness was measured by placing the piles on a flat surface and measuring the maximum distance between the deformed columns and the surface. Additional details of the testing and observed behavior of the columns prior to repair are summarized elsewhere [11].…”

“…Karagah et al [11] reported the properties of the structural steel that were used for the tested columns. The tensile properties were obtained from two tensile coupons taken from the web and four coupons taken from the flanges of the tested section.…”

Behaviour of concrete-filled steel tubular members under pure bending and acid rain attack: Test simulation

“…Sultana et al (2015) studied the compressive strength of stiffened panels with pitting corrosion. Karagah et al (2015) tested the performance of corroded steel columns under axial compression. Han et al (2012Han et al ( , 2014 and Hou et al (2016) carried out experiments with 22 beams and 34 stub columns under a sustained load and with chloride corrosion.…”
