In this study, axially loaded compression experiments at elevated temperatures for steel column specimens with high-strength bolted connections providing clearance-gaps between column faces were conducted to clarify the fire resistance performance and the surface-touch behavior of the column cross-sections in the connection after the slip-behavior. The steady state, transient state, and thermal stress experiments at the elevated temperatures were conducted. Experimental results show that the slipped column connection at elevated temperature exhibited the stable load-bearing capacity because the column cross-section surfaces in the connection were wholly touched and the axial load was transmitted by the surface-touch without the bolt shear-fractures.

To investigate stress and deformation behavior of steel structure in fire, it is important to consider behavior of friction type high strength bolted joints during not only heating phase but also cooling phase. The purpose of the present paper is to consider stress and deformation behavior of the joints under cooling phase. This paper reports on results of the tensile test after fire, displacement restraint test under cooling phase and numerical study of the restraint test. As a result, in case of the joint which designed to investigate the behavior of tear-out failure, the sufficient deformation capacity was confirmed because of the ductility of the plates with a bolt hole.

The behavior of steel floor structures under elevated temperatures is numerically simulated using detailed FEM models, considering inelastic temperature-dependent material properties and large deformation. The component models are independently validated with existing experimental data. Deflection of the beams and slabs, and failure of simple bolted connections at elevated temperatures are evaluated. Using these models, the behavior of a one-bay floor structure in fires is simulated. It is found that catenary effect can carry the vertical load, under different damage conditions such as shear failure of the bolted connections, the slab cracks and yielding of the reinforcement in the slabs.
