The static strength of uniplanar and multiplanar connections between I-beams and RHS columns loaded by axial compression
- Delft Univ. of Technology (Netherlands). Dept. of Civil Engineering
This study is a part of a large project on semi-rigid connections between I-beams and RHS columns in which various geometries and load combinations are being investigated. In this paper, the results of a parameter study on connections between I-section beams and rectangular hollow section columns loaded by axial compression on the beams are presented. Fourteen uniplanar connections and eleven multiplanar connections have been investigated. The most important geometrical parameters which determine the connection strength and behavior have been studied. Five load ratios are considered for each multiplanar connection so that the multiplanar load effects are obtained. By comparing the results from the present research and the numerical results of previous research on the corresponding connections with one level of plates to RHS columns, the influence of the second flange and web of an I-beam on the behavior of the connections is determined. Based on the analytical models and the numerical results, strength formulae for both uniplanar and multiplanar I-beam to RHS column connections loaded by axial compression are derived.
