Abstract
A mathematical procedure is described for predicting displacement and stress histories of reinforced concrete slabs in fire environments using a computer program, FIRES-SL(FIre REsponse of Structures- SLabs). The temperature distribution histories used if FIRES-SL are obtained either from experimental results or from a one-, two-, or three-dimensional thermal analysis based on selected fire models. In a fire environment, thermal gradients and dilatation are sources of internal stress from local restraints within the slab and global restraint from the overall structural system. Structural response is determined in terms of displacements, internal forces, stresses and strains in concrete and steel reinforcement, and current states of concrete (cracking and crushing) and steel reinforcement (yielding).
