Overview of research on fire effects in RC elements and assessment of RC structures after fire

Procedures for estimating damage and remaining bearing capacity of RC structures after fire are presented in the paper. The paper describes the effect of fire on structures, the danger it poses for the loss of human lives, and financial losses it may generate. The damage to structural RC elements of a column, beam, slab, wall, and connection details, is presented in the paper. Although RC elements are generally considered to be fire resistant, their physical and mechanical characteristics are greatly influenced by temperature, while the bearing capacity before and after fire can be determined through a number of different methods that are presented in the paper. An overview of condition assessment for RC structures after fire is proposed, and methodology for taking further action is presented.
