A Review of Precast Concrete Beam-to-Column Connections Subjected to Severe Fire Conditions

Fire exposure can have a significant impact on the structural integrity and robustness of precast concrete beam‐to‐column connections. Given the importance of fire safety in the design of a structure, it is critical to understand the damage that may occur in the event of a fire to be able to prevent the building from collapsing. No comprehensive study has been carried out to determine the effects of fire on semirigid and pinned concrete beam‐to‐column connections. Most studies focused on the impact of exposure of rigid concrete beam‐to‐column connections to high temperatures. This paper is a comprehensive review of the literature on the performance of precast concrete beam‐to‐column connections under fire conditions. The key areas in this review are the moment‐rotation‐temperature characteristics and fire effect on precast concrete beam‐to‐column connections. This paper focuses primarily on the case studies of real fires, large‐scale fire tests, computer simulations and analytical models, fire resistance tests on the connection elements, and assessment and rehabilitation of fire‐damaged precast concrete. The paper also discusses the current issues and possible challenges.
