“…6a shows the most damaged region of the column at the end of testing, which illustrates the failure mode and the critical diagonal cracks. It should be noted that the diagonal crack angle of 33 o is consistent with the findings of a previous experimental study conducted by Ou and Kurniawan [51], which concluded that the critical diagonal crack angles with respect to the longitudinal axis of the column were smaller than 35 o .

“…The similar results on seismic behavior of slender columns reinforced with high-strength longitudinal reinforcements also can be found in the research literatures [14,[20][21]. Ou et al [11][12] and Sokoli et al [13] studies the shear behavior of large-scale concrete columns reinforced by high-strength steel and concluded that bond degradation around the longitudinal reinforcement occurred and the shear strength of columns was affected by axial compression. This suggests that the minimum shear reinforcement equation need to consider the influence of axial compression.…”

“…As a result, using high-strength steel has become widespread in concrete structural application. However, limited researches have been carried out to obtain eccentric compressive behavior of concrete columns reinforced with high-strength steel, although many scholars [9][10][11][12][13][14] have conducted studies on high-strength steel used in concrete columns.…”

The use of new developed high-strength steel in concrete members can reduce steel bars congestion and construction costs. This research aims to study the behavior of concrete columns reinforced with new developed high-strength steel under eccentric loading. Ten reinforced concrete columns were fabricated and tested. The test variables are transverse reinforcement amount and yield strength, eccentricity, and longitudinal reinforcement yield strength. The failure patterns are compression and tensile failure for columns subjected to small eccentricity and large eccentricity, respectively. The same level of post-peak deformability and ductility only can be obtained with lower amount of transverse reinforcement when high-strength transverse reinforcements are used in columns subjected to small eccentricity. The high-strength longitudinal reinforcement can improve bearing capacity and post-peak deformability of concrete columns. Besides, three different equivalent rectangular stress block (ERSB) parameters in predicting bearing capacity of columns with high-strength steel were discussed based on test and simulated results. It is concluded that the Code of GB 50010-2010 overestimates the bearing capacity of columns with high-strength steel, whereas bearing capacities computed using Codes of ACI 318-14 and CSA A23.3-04 agree well with test results.

Use of high-strength reinforcement in earthquake-resistant concrete structures

to study and make recommendations concerning the utilization of high-strength steel reinforcing bars in concrete structures subjected to earthquake ground motion. This work grew out of the ATC-57 report, The Missing Piece: Improving Seismic Design and Construction Practices (ATC, 2003), which defines a roadmap for the NIST problem-focused research and development program in earthquake engineering. The ATC-57 report recommended that NIST examine new technologies that can improve construction productivity, such as high-strength reinforcement. The NEHRP Consultants Joint Venture is indebted to the leadership of Dominic J.
