“…Thus, some researches have been carried out to investigate the thermal cracking behaviors of concrete at elevated temperatures, and the vital governing factors for high-temperature cracking of concrete, such as steam pressure, external load, thermal stress as well as some fracture parameters including the critical fracture toughness and fracture energy. Based on the research of concrete damage behavior at elevated temperatures in material level, some fire damage assessment models and methods of concrete structures in structural level (Behnam et al., 2013; Molkens et al., 2017; Qin et al., 2022; Ryu et al., 2018; Vitorino et al., 2020), have been developed and utilized to explore the relationships between fire temperature and the residual load-bearing capability of engineering structures, especially for post-earthquake fires.…”

A multi-scale model is established to describe the relationship between the macroscopic damage evolution and microscopic cracks behaviors of concrete at elevated temperatures. The evolution equation of the ideal microscopic crack system of concrete at elevated temperatures is deduced for construct the model, which can predict the microscopic crack density and macroscopic damage of concrete at elevated temperatures. The multi-scale model fuses some advantages of the traditional microscopic and macroscopic damage models. Finally, multi-scale damage of a concrete block under high temperature is predicted and compared with the corresponding experimental results, which is utilized to support the ability of the developed model. The results show that the developed multi-scale model can be used to evaluate fire damage of concrete structures in macro-scale as well as explain its physical mechanisms in micro-scale.

“…In the numerical investigations of RC elements, several commercial codes can be used to simulate the fire performance of beams according to ISO 834 [6] heating curves, or in some cases, the ASTM E119 [7] standard is also considered in investigations. The concrete and steel bars can be modelled, and their interactions can also be simulated in finite element analysis [8] and in some finite elements, the thermal element must be created by the user to be able to evaluate heating effects in structural members after the seismic analysis.…”

This review aims to investigate the recent advancements in the performance of earthquake-damaged reinforced concrete structures subjected to fire loading and the damages that are induced by fire to reinforced concrete structural elements with damage due to seismic loads. The first part of the paper provides a general understanding of the Post-Earthquake Fire (PEF) effect on reinforced concrete structures, and some statistics regarding the previous earthquake casualties and amounts of destruction in different regions of the world are addressed. In the second part of the investigation, an in-depth review of the experimental and numerical procedures of PEF analysis in concrete columns, beams, slabs, and full-scale RC frames and the types of damages in RC members due to PEF have been presented, giving a general review of the results and conclusions in previous research in PEF in different reinforced concrete structures. In the end is discussed the concept of hybrid fire simulation, its applications in engineering problems, the methodologies that consider full interaction effects as well as recent breakthroughs in studying PEF using Real-Time Hybrid Simulation.
