In this study, the mechanical performance of lightweight concrete exposed to high temperature has been modeled using genetic programming. The mixes incorporating 0%, 10%, 20% and 30% silica fumes were prepared. Two different cement contents (400 and 500kg/m 3 ) were used in this study. After being heated to temperatures of 20°C, 200°C, 400°C and 800°C, respectively, the compressive and splitting...
