Abstract
The structural fire performance tests for beam-to-column connections are critical in determining their fire performance at high temperatures. The current standard fire testing methods provide the procedures for establishing the fire resistance of each construction element exposed to a standard fire. However, these methods cannot verify the fire behaviour of the connections between building elements. Researchers have performed numerous fire tests on beam-to-column connections despite the lack of structural fire performance testing methods. This paper presents a comprehensive literature review of the structural fire performance testing methods for beam-to-column connections. The major areas in this review are travelling fires, development of travelling fires on beam-to-column connections, fire testing considerations, fire testing criteria, recent fire testing, and loading applications. This paper identifies the key issues and challenges of the structural fire performance testing methods for beam-to-column connections. Finally, this paper provides recommendations and discusses the way forward for structural fire performance tests on beam-to-column connections.

Introduction and ObjectivesStructural fires occur primarily in residential, commercial, or community-based buildings
The local fuel at point A is completely burnt and the structure begins to cool, and the fire damage sustained by the structure, such as deflection, crack, and spalling, becomes apparent. e fire travels vertically to the upper floor from point B to C through a damaged structural joint, unprotected service ducts, combustible façade materials, and unprotected openings, such as non-fire-rated windows. e flame movement increases the temperature at the top, creating the far field
Even though the standard time-temperature fire curves do not have a decay phase at the end and appear more severe than the real fire, they are suitable for conducting fire tests for the growth, burning, and decay phases. ere are many studies on the cooling phase of steel and composite beam-to-column connections, but there is a dearth of studies on the structural response of the reinforced concrete (RC) beam-to-column connections in the cooling phase. e literature review revealed that there are three issues with the test load applied to the beam
Summary
Structural fires occur primarily in residential, commercial, or community-based buildings. The standard fire testing methods do not have the procedures for verifying the fire behaviour of connections between building elements [10, 11]. Is paper presents a comprehensive literature review of the structural fire performance testing methods for beam-tocolumn connections. In stage one of the literature review, the authors searched and screened the Web of Science and Scopus databases for the literature concerning building fires and fire testing of beam-to-column connections and defined the critical concept in building fires, including travelling fires and standard fires. This paper provides the recommendations and presents the way forward for the structural fire performance tests of beam-to-column connections to help steer future research in structural fire engineering, large-scale experimental research
