The behavior of concrete, as well as that of all cohesive-frictional materials, is characterized by a strong dependence on hydrostatic pressure and strain rate sensitivity. The stress–strain response is nonlinear and, ...

The effect of transverse or perimeter confining of concrete by a reinforcement that simulates the three-dimensional behavior of the material has been subject of research since 20th century. The results have indicated, ...

This paper presents an experimental analysis of the confinement effects in steel-concrete composite columns regarding two parameters: concrete compressive strength and column slenderness. Sixteen concrete-filled steel ...

Observations following recent earthquakes, and from structural testing, indicate numerous brittle compression failures in rein-forced concrete seismic-resisting walls. This is unexpected, as most seismic-resisting walls ...

This paper focuses on the reformulation of the internal functions of the performance-dependent failure criterion (PDFC) for concrete, proposed by the authors, and its validation for different concrete qualities and stress ...

An experimental study of the confined compression behavior of concrete has been performed using 150x300 mm cylindrical specimens subjected to hydrostatic pressure in a triaxial cell and axial loading through a servo-hydraulic ...

The use of fiber reinforced polymers (FRP) to strengthen reinforced concrete (RC) columns through concrete confinement has proven to be a viable alternative, especially in the case of circular bridge piers. FRP is a composite ...

This paper presents an investigation of design code provisions for steel-concrete composite columns. The study covers the national building codes of United States, Canada and Brazil, and the transnational EUROCODE. The ...

In this article, the formulation and verification of a nonlinear quadrilateral layered membrane element with drilling degrees of freedom for the nonlinear analysis of reinforced concrete (RC) walls under static and cycling ...
