Abstract
Although beam-to-column joints are a critical part of steel and composite framed structures, very few tests have been conducted under fire conditions. Of the tests conducted, only a limited range of joint types has been studied. The main reason for this is the high cost associated with elevated-temperature tests. This paper presents the results of an experimental investigation of typical steel extended end-plate beam-to-column joints at elevated temperatures. Six beam-to-column joints were tested. These included three tests conducted at 400, 550, and 700°C, and another three tests on specimens at 700°C with different axial compression forces applied to the beams to simulate restraint effects. Moment-rotation-temperature characteristics are summarized in order to investigate the degradation of this type of steel joint at elevated temperatures.
