Load Introduction in Composite Columns with Concrete Filled Hollow Sections

Experiments on rectangular concrete-filled steel tubes loaded axially on a partially stressed cross-sectional area

“…Bergmann [10], Cai [11], Porsch and Hanswille [12] and Han et al [13][14][15] experimentally investigated the behaviour of CFST stub columns with circular and square sections loaded on partial cross-sectional area. It was found that, due to the partially loaded effects, the behaviour of such composite columns was significantly different from those of the fully loaded members.…”

A comparative study of environmental performance between CFST and RC columns under combinations of compression and bending

“…However, square and rectangular columns are favored by engineers because of their simple joint configuration, good stability, suitable shape for architectural designs and current popularity (Yang et al, 2014). Some researchers (Porsch and Hanswille, 2004;Han, 2009, 2011) The parameters, including the steel strength, cross-section and steel ratio, of six concrete columns are summarized in Table 1. This study was developed based on structural performance studies, and the parameters applied were in accordance with those investigations.…”
