Sound casting is necessary for obtaining high-quality concrete structures. A quantitative evaluation for the sound casting can be achieved by describing the passing and filling ability of concrete. This study proposes a generalized model to predict the filling ability of concrete in steel-plate concrete panels. The panels include periodic arrayed studs; their density is much higher than that of general reinforcements in concrete structures. The permeability describing the concrete flow resistance by the periodic arrayed studs is numerically evaluated considering their geometrical distribution. Two algorithms based on the porous-medium analogy are then proposed to simulate the filling of concrete.
