“…Therefore, the mechanical properties of the material depend on the loading and temperature history. If a structure does not collapse when it reaches the maximum fire temperature, it may collapse during the cooling phase [41]. Real fires have many different temperature-time relationships in the real time.…”

“…In the study, the ISO 834 fire curve was used to heat the bolts and plates (Figure 9). Yang et al [40] and Hosseini et al [41] added the cooling phase to the ISO 834 fire model to examine the effects of the cooling and post-fire phases [42]. To evaluate a structure exposed to fire, the residual mechanical properties of the structural materials must first be assessed.…”

Heat affects the mechanical properties of steel and the bearing capacity of steel structures, with joints being a crucial factor in determining their behavior. Steel can regain its mechanical properties that are lost owing to heat if the temperature remains below 600 °C, allowing for the possibility of reusing steel after cooling. In such cases, it becomes essential to assess the damage caused by heat exposure to decide whether to demolish the structure or continue using it. However, continuing its usage requires anticipating the potential negative effects of heat. To achieve this, it is necessary to determine the behavior of steel joining tools experimentally or numerically after exposure to heat. This study aims to ascertain the post-fire behavior of various end-plated beam and column connections, providing a cost-effective alternative to expensive fire experiments. Three different end-plated combination models were heated to a specified temperature, and steel frames were constructed after the elements cooled. Six three-point bending tests were conducted, and the experimental data obtained were validated using finite element models. The results indicate that the temperature causes a reduction in the bearing capacity of the joint, and the length of the end plate has a significant effect on the connection behavior. The finite element model validated by experiments is expected to facilitate numerical studies with different characteristics.
