Behavior of concrete columns reinforced with high-strength ...

20/10/2018  In this study, high-strength steel (HSS) reinforcement with a yield stress of about 600 MPa was used in reinforced concrete columns to reduce both the reinforcing bar congestion and the construction costs. For this purpose, 16 square concrete columns reinforced with either the conventional normal-strength steel (NSS) or HSS rebars were subjected to axial and eccentric

07/07/2018  In addition, the area of confined concrete is higher in GSEA reinforced concrete members than in steel bar reinforced members, which results in higher strength and ductility. The experimental program involved testing of 20 square, high-strength concrete (HSC) specimens under concentric axial load, eccentric axial load, and four-point loading. The specimens were reinforced longitudinally with ...

Structural Behavior of Reinforced High-Strength Concrete ...

The high compressive strength of high-strength concrete is especially advantageous in compressed members such as columns, which can be made more slender and, consequently, make economic benefits possible. However, the behavior of high-strength concrete columns is not yet fully understood. This thesis deals with the behavior of reinforced normal and high-strength concrete columns under ...

Experimental results are presented for a new method of reinforcing concrete columns with galvanized steel equal-angle (GSEA) sections. For the same cross-sectional area, a GSEA section has a higher second moment of area than a conventional steel bar, which leads to a higher bending stiffness of the GSEA reinforced concrete member. In addition, the area of confined concrete is higher in GSEA ...
