EXPERIMENTAL STUDY OF CONCRETE-FILLED STEEL MEMBERS WITH CIRCULAR CROSS SECTION SUBJECTED TO BENDING AND TORSION

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 ...

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...

Numerical Analysis of Concrete-Filled Circular Steel Tubes

Seismic Design of Concrete-Filled Circular Steel Bridge Piers

The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...

Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...
