摘要: The concept of grading material composition in a predetermined direction to target multiple objectives and functionality is applicable the layering positioning different materials at specified depths. From fracture mechanics perspective, this study explores advantages using functionally graded concrete (FGCMs), that is, plain fiber-reinforced (FRC), two distinct layers. energy (G) residual load capacity (Pδ) two-layered beams are investigated by means numerical simulations with cohesive zone model (CZM) implemented finite element framework. required parameters for defining CZM obtained from individual tests FRC materials. analyzed effects thickness position (whether top or bottom beam) on resistance beam. A cost-benefit analysis showed placed bo...
