This paper presents an effective reliability analysis procedure and proposes the system resistance factors for design of steel-concrete composite frames that comprise concrete-filled steel tubular (CFST) columns beams. Advanced is employed to predict ultimate using fibre beam-column elements in OpenSees. The obtained predictions load-carrying capacity compare well with experimental results mean...

In the present study, non-linear finite element analyses are carried out on the slender reinforced concrete columns wrapped using CFRP composite with different cross-sectional shapes having the same area. Thickness of the CFRP wraps, concrete compressive strength, corner radius, loading condition, slenderness ratio and column size are the main parameters of this study. According to this, four d...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...
