Ductility Improvement of High-Strength Concrete Columns ...

High-Strength Concrete 49 load. Such ductility may decrease further with the use of higher strength of concrete. Especially when using the high-strength concrete in high-rise building frames, seismic design of structure may be impossible without enhancement of column ductility. Thus, in this study, eight reinforced concrete columns with lateral ...

01-11-1990  The concrete compressive strengths were 85.7 and 115.8 MPa, respectively. Volumetric ratio of lateral reinforcement was 1.6 percent in all specimens. Test results indicated that the very large ductility could be achieved by using high yield strength lateral reinforcement, even for such high-strength concrete columns.

The usage of high strength concrete (HSC) in reinforced concrete (RC) bridge columns in earthquake prone regions is hindered due to the brittle nature of HSC. Passive lateral confinement does not improve the ductility efficiently since HSC exhibits low lateral expansion under axial loads.

Improving flexural ductility of high-strength concrete columns

Session - Concrete and Composite Structures (I)High-strength concrete (HSC) has been widely used in the column construction of tall buildings because of its larger strength-to-weight ratio. The current design of HSC columns focuses on providing adequate flexural strength but not on flexural ductility.

07-11-2016  High-strength concrete (HSC) is increasingly used for the construction of tall buildings and long span bridges. However, most engineers just focus on how to better utilize the strength potential of HSC and little attention is paid to ensure that the HSC structures would have sufficient ductility.

22-05-2003  While column ductility can be increased through confinement, the ACI 318-02 (1) confinement requirements are intended for normal-strength concrete columns and are not applicable to columns cast from high-strength concrete. A displacement based design procedure has been developed for the confinement of high-strength concrete columns.
