Uniaxial and triaxial behavior of high strength concrete with and without steel fibers
… and triaxial compression behavior for both high strength concrete (HSC) and steel fiber reinforced high strength concrete (SFHSC). The experimental study mainly focuses on the octahedral shear stress strain relationship of those two types of concrete, which is adopted as the basis to develop …

Shear Behavior of Reinforced Concrete Beams and Prestressed Concrete Beams
"In the last decades, developments in high-strength concrete materials are rapid, but codes of practice still limits the concrete compressive strength in design of concrete structures due to a lack of experimental research data. As an effort to overcome the limitation to the use of high strength …

Axial load capacity of circular steel tube columns filled with high strength concrete
… examines the axial load capacity of circular Concrete Filled Steel Tube columns using High Strength Concrete (CFST-HSC). Emphasis is drawn to the enhanced axial capacity of short columns attributed to the lateral confinement of the concrete infill provided by the steel encasement. The degree …

Optimal applications of high-strength concrete in structural walls of tall buildings
This study examines the application of high-strength concrete (HSC) in structural walls of tall buildings. Emphasis is put on the cost-benefits corresponding to the use of higher concrete strengths. The parameters included in the cost analysis are: the material cost of concrete and reinforcing …

Monolithic beam to external column joints in reinforced concrete
The benefits of high strength concrete (HSC) in the construction of multi-storey buildings are commonly acknowledged. Past researchers have investigated the suitability of design codes for the use of HSC [1]. However, there are concerns about the shear behaviour of HSC beams and BCJ used in the …

Circular Reinforced Concrete Columns Damaged By Fire and Retrofitted With Cfrp and Steel Jacketing
… decades, the post-fire behavior of reinforced concrete (RC) columns with normal and high-strength concrete has become an important research topic. Numerous studies have demonstrated that RC columns exhibit good fire resistance owing to the thermal properties of concrete. Therefore, reinforced …

Inelastic web crushing performance limits of high-strength-concrete structural walls
… of the three new toll bridges in California has highlighted the application of the hollow rectangular bridge piers with highly-reinforced boundary elements and the connecting walls. However, current conservative design approaches result in massive cross sections that can lead to increased …

Response of high strength concrete columns under fire-induced biaxial bending
Reinforced concrete (RC) columns, under fire conditions, can experience biaxial bending which can arise due to eccentricity in loading, uneven spalling, or due to significant thermal gradients generated through 1-, 2-, or 3-sides of fire exposure. High strength concrete (HSC) columns are especially …

Engineering properties and structural behaviour of high strength reinforced concrete beams
High Strength Concrete (HSC) has become a viable alternative to lower strength concrete. However, its utilisation is increasing faster than the development of suitable design recommendations. This is because limited and diverse investigations have been carried out concerning engineering properties …

Axial compressive behaviour of FRP-confined high-strength concrete
External confinement of concrete columns with fibre-reinforced polymer (FRP) sheets has been shown to lead to significant improvements on the axial compressive behaviour of these columns. This application of FRP composites is effective as a confinement material for concrete, in both the seismic …
