Structural performance of steel reinforced concrete T-shaped columns exposure to high temperature

Post-Fire Behavior of Cross-Shaped Steel Reinforced Concrete Columns: Simulation and Analytical Expressions

“…Unfortunately, high-rise building fires are not uncommon, posing a serious threat to people's safety. After exposed to fire, the strength and rigidity of the steel-concrete composite members are lost, so it is essential to reevaluate the residual bearing capacity to take appropriate reinforcement measures to ensure that the structure can withstand the corresponding load [1][2][3][4] and continue to put into use. However, the core issue of repair assessment is how to determine the residual bearing capacity of the structure after fire, which has not been resolved yet.…”
