... with an increase in exposure duration. Moreover, GC outperforms CC mixes in the case of thermal resistance. GC mixes exhibited higher residual strength (up to 17.2 MPa after 30 min and 4.5 MPa after 120 min), lower porosity (0.03%) and reduced crack width (0.02 mm), demonstrating improved fire resistance...

... steel, widely used in construction due to its durability and corrosion resistance, can experience mechanical property degradation under extreme temperatures, potentially leading to structural failure. This study aims to evaluate the fire resistance of stainless steel beams using numerical simulations...

... the parametric studies illustrate that decreasing the gap size and the top angle size and increasing the top angles thickness affect fire behavior of top-seat angle joints and decrease the beam deflection by about 16% at temperatures beyond 570 °C. Also, the fire-resistance rating of the beam with seat angle...
