Abstract
The connection behaviour of square hollow section as column welded with I-section as beam (SHCWIB) is commonly used in the construction of modern steel buildings. The behaviour of such connections under elevated temperature or fire load is limited. In this paper, the experimental studies on the behaviour of SHCWIB connection, subjected to an elevated temperature (of 600 °C) and mechanical load, are presented. The beam-to-column connection is initially exposed to the elevated temperature and then cooled to the room temperature. Pre-thermally damaged connection is subjected to an increasing monotonic load while the column member is subjected to a constant axial compression. It is observed that the connection failed at lower loads due to the combination of P-delta effect and pre-thermal damage.
