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...

Novel packed-capillary columns for gas chromatography were developed with a thin-wall stainless-steel capillary of 1.0 mm i.d.; and rapid temperature-programmed separations have been carried out after a basic evaluation concerning the compatibility of these columns to the temperature program. With a numerical integration method, the retention of several test analytes during temperature-programm...

A significant amount of research has been conducted worldwide on the behavior of concrete filled steel tubes (CFTs) in the past five decades. This report provides a summary of the behavior and experimental work of concrete filled steel tube members, connections, and frames that are reported in detail in the literature. These published studies have been summarized with an emphasis on experimenta...

The article is aimed at the statistical and sensitivity analysis of the ultimate limit state of steel frames. Load–carrying capacity is calculated for steel plane frames with columns loaded in tesion or compression. The Monte Carlo based procedures are used for statistical analysis and for computing the full set of first order and second order sensitivity indices of the model. System imperfecti...

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...

Steel Plate Shear Wall (SPSW) is made from thin steel plate which in turn are framed by the beams and columns of structural system. In recent year they are proved to be very effective and economical for resisting lateral loads such as earthquake and wind loads.The present work targets to study the behaviour of single frame SPSW with different plate thicknesses, rigid and non-rigid frame members...

steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...
