In this paper, full-scale reinforced concrete slabs are analyzed under thermal-mechanical loads in fire conditions. The rectangular one-way slabs including a simply supported slab and a three-span continuous slab are concerned in the analysis. Finite element simulation is carried out by using the ABAQUS program to evaluate the non-uniform temperature distributions in thickness of the slabs and to analyze the deformation and stress redistribution of the slabs at elevated temperatures. Sequentially coupled thermal and structural analyses are performed to simulate the responses of the slabs in fire conditions. Deformation and strength of the slabs under thermal and mechanical loads are discussed. The numerical results are compared with the experimental ones and good agreements are observed. The analysis results show that the main reinforcement ratio has significant effects on the deformation and strength of the slabs at elevated temperatures and the three-span continuous slab has better performance of fire-resistance than the simply supported slab.

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.
