This paper conducts an experimental study on the axial compressive performance of FRP-steel-concrete composite columns. Nine short columns were produced and evaluated in study, comprising three concrete-filled steel tube reference six columns, respectively denoted as “reference columns” “composite columns”. Two categories failure modes, including shear waist drum, observed from experiments. The...

Concrete filled steel tube (CFST) columns are being popular in civil engineering due to their superior structural characteristics. This paper investigates enhancement axial behavior of CFST by adding fibers plain concrete that infill tubes. Four specimens were prepared: two square (100*100 mm) and circular (100 mm diameter). All 60 cm length. Plain mix reinforced with used columns. Ultimate loa...

The worldwide progress to date in experimental and computational studies on composite frame structures having rectangular concrete-filled steel tube (RCFT) beam-columns and steel girders and braces has revealed their exceptional seismic resistance. In this paper, a computational study to develop reliability-based performance-based seismic design guidelines of RCFT members is presented. A three-...

Lightweight steel framing is a method in housing and construction that have been widely used in lightweight steel construction. In this method, the structure is built by cold formed steel elements. They are cost-effective, light, and easy to assemble. However, the performance of lateral load resisting systems in cold-formed steel structures specially the behavior of cold-formed steel shear wall...
