“…In addition, tests to study the behaviour of beamto-column joints at elevated temperatures were carried out by British Steel [4], Lawson [5] and Leston-Jones [6]. An experiment study was performed on four full-scale extend endplate joints in fire and a spring-component modelling was presented to predict the rotation of the joints in fire by Wei-yong Wang et al [7]. These tests provide useful data for theoretical study.…”

“…usually beneath a composite floor. In conventional analysis and design of steel and composite frames, beam-to-column connections are assumed to behave either as 'pinned' or as fully 'rigid' joints [1,2]. Although the pinned or rigid assumption significantly simplifies analysis and design procedures, in practice, the actual joint behavior exhibits characteristics from a wide spectrum between these two extremes.…”

Recent structural collapses caused by fire have focused attention on research concerning fire safety in building design. Steel connections are an important component of any structural steel building as they provide links between the principal structural members. Considering the importance of this matter this paper describes a spring-stiffness model developed to predict the behavior of bolted angle connections bare-steel joints at elevated temperature. The joint components are considered as springs with predefined mechanical properties i.e. stiffness and strength. The elevated temperature joint's response can be predicted by assembling the stiffness of the components which are assumed to degrade with increasing temperature based on the recommendations presented in the design parameters code. Comparison of the results from the model with existing experimental data showed good agreement. The proposed model can be easily modified to describe the elevated temperature behavior of other types of joint as well as joints under large rotations.

“…Most of these studies focused on the bolted connections, and the specimens were isolated beam-to-column subassemblages [7][8][9]. Unlike the previous experimental studies using isolated specimens, Ding and Wang [10] utilized complete ''rugby goalpost'' subassemblage frames to conduct steel beam to concrete-filled tubular column connection tests to four types of connections.…”
