“…Recently, two robust simplified connection models have been developed by the authors [15,16] for modelling the end-plate and partial end-plate connections between steel beams and columns in fire. The proposed models are based on the two-node connection element framework developed by Huang [21].…”

“…For modelling the behaviour of connections which connect beam to flange of column (majoraxis) at elevated temperatures, two simplified connection models were developed [15,16] and incorporated into software VULCAN. As described in Reference [15], a simplified model has been proposed to predict the performance of flush and extended end-plate beamto-column flange (major-axis) connections in fire.…”

“…As described in Reference [15], a simplified model has been proposed to predict the performance of flush and extended end-plate beamto-column flange (major-axis) connections in fire. The connections failure due to bending, axial tension, compression and vertical shear are all taken into account, as well as the impact of axial tensile force of the connected beam on the connection.…”

“…The partial end-plate connections are adopted to connect secondary beams to columns, and primary beams to secondary beams, respectively. These two types of the connections are modelled using the simplified connection models developed by the authors [15,16]. The proposed two connection models have good numerical stability under a static solver condition, and can be used for large scale modelling of composite buildings in fire.…”

According to full-scale fire tests, it is noticed that tensile membrane action within the concrete floor slabs plays an important role in affecting the fire resistance of composite buildings. It is well known that the development of tensile membrane actions relies on the vertical support along the edges of the slab panel. However, there is at present a lack of research into the influence of vertical supports on the tensile membrane actions of the floor slabs. In this paper, the performances of a generic three dimensional 45m x 45m composite floor subjected to ISO834 Fire and Natural Fire are investigated. Different vertical support conditions and three steel meshes are applied in order to assess the impact of vertical supports on tensile membrane action of floor slabs. Unlike other existing large scale modelling which assumes the connections behave as pinned or rigid for simplicity, two robust 2-node connection element models developed by the authors are used to model the behaviour of endplate and partial end-plate connections of composite structures under fire conditions. The impact of connections on the 3D behaviour of composite floor is taken into consideration.The load-transfer mechanisms of composite floor when connections fail due to axial tension, vertical shear and bending are investigated. Based on the results obtained, some design recommendations are proposed to enhance the fire resistance of composite buildings.

In this paper, the performances of a generic three dimensional 45m x 45m composite floor subjected to ISO834 Fire and Natural Fire are investigated. The influences of reinforcing steel mesh and vertical support conditions on the tensile membrane action of floor slabs are investigated in details. Two robust 2-node connection element models developed by the authors are used to model the behaviour of end-plate and partial end-plate connections of composite structures under fire conditions. The impact of connections on the 3D behaviour of composite floor is considered. Based on the results obtained, some design recommendations are proposed to enhance the fire safety design of composite buildings.
