Plane Steel Frame

In this paper, co-rotational total Lagrangian finite element formulation is derived, and the corresponding numerical model is developed to study creeping behavior of plane steel frames in fire. Geometrical nonlinearity, material nonlinearity, high temperature creeping, and temperature rising rate are taken into account. To verify accuracy and efficiency of the numerical model, four prototypical numerical examples are analyzed using this model. Results are in a great agreement with solutions in literatures. Then the numerical model is used to analyze creeping behavior of the plane steel frames when temperature is lowering. The numerical results have significant contribution to resistance and protection for steel structures against disastrous fires.

Elevator Evacuation

As tall buildings are becoming more common there is a need to examine alternative evacuation strategies. In response to this many new high-rise buildings are equipped with evacuation elevators. Traditionally, elevators have not been used for evacuation and people have been instructed to avoid using them in fire emergencies. It might therefore be quite challenging to get people to use elevators for evacuation. If evacuation elevators are to be perceived as an attractive option people must be given appropriate information and guidance. In the following paper, previous research is examined in order to identify the information required to convince people to use evacuation elevators. In addition, a theory that can aid the design of evacuation systems, i.e., the tools for conveying the information, is presented and applied. Finally, a research strategy for developing and testing new evacuation systems is presented.

Fire Conditions

A state-of-the-art review of the behaviour of steel frame structures in fire is presented. Results from different studies indicate that the behaviour of a complete structure is different from that of a single structural member under fire conditions from the point of view of fire resistance. Earlier studies also show that analysis and design of steel structures against fire based on their overall behaviour could lead to a reduction or the elimination of applied fire protection to certain structural members. The effects of continuity, restraint conditions, and load ratio on the fire resistance of frame structures are discussed. The beneficial aspects derived from considering overall structural rather than single-member behaviour in fire are illustrated through the analysis on two one-bay, one-storey, unprotected steel portal frames, a column, and a beam. Also comparison is made between the performance of a beam with different end restraints in fire. Results from the analyses indicate that the fire resistance of a member is increased when it is considered as part of a structure compared with when it is considered as a single member.Key words: steel, frames, fire resistance, buckling, loads, overall structural behaviour.
