Behavior of an Internally Confined Hollow Reinforced Concrete Column with a Polygonal Cross-Section

Shear strength model of reinforced concrete circular cross-section members

A shear capacity model of reinforced concrete members with circular cross section transversely reinforced with circular hoops has been developed. The proposed model is based on the truss analogy by adding a concrete contribution term to the capacity of the shear reinforcement. An additional deviatoric shear resisting th c curv pres nism ste ved und ctor mechanism of hoops present solely in memb...

Shear Area of Reinforced Concrete Circular Cross-section Members

The shear strength of reinforced concrete members without shear reinforcement is related to the shear stress carried by the concrete effective shear area. For rectangular sections the effective shear area represents the area corresponding to the effective depth. However, for circular sections this area is not as readily defined. Different empirical proposals have been suggested recently but no ...

Effect of ply configuration on hollow square reinforced concrete columns confined with Carbon fibre-reinforced polymer (CFRP)

This paper presents results of testing twelve hollow square reinforced concrete specimens wrapped with Carbon fibre reinforced polymer CFRP. The effect of ply configuration on the behaviour of the specimens is investigated. All specimens were 800mm high and had the dimensions of 200mm× 200mm in cross-section and a hollow core of 80mm× 80mm. The specimens were divided into four groups with three...

Confined precise removal of reinforced concrete

Decontamination and remote handled shredding of reinforced concrete is fundamental to the decommissioning process of nuclear installations. The main target is to select and remove the contaminated material and to return the remaining material to the regular recycling loop, since the contaminated material usually only provides for a fraction of the total mass. Various methods, which are continuo...
