Abstract

Double Skin Tubular Beam-Columns Under Reversed Lateral Loading

Author(s): T. S. Parvati and P. S. Joanna

Concrete filled double skin tubular (CFDST) members consist of two concentric steel tubes with concrete sandwiched between them. This paper presents an experimental investigation on the concrete filled double skin tubular beam-columns subjected to reversed lateral loading. The specimens consist of cold formed steel square tube as it’s outer and inner tube with fly ash concrete infilled in between the two tubes. The behaviour of the fly ash infilled CFDST beam-columns with bolted connections under constant axial load and reversed lateral loading were examined. The results are compared with the concrete filled steel tubular beam-column (CFST) specimens, which were considered as the control specimen. The specimens with square cross-section exhibited better load carrying capacity than the control specimen.
