Adaptive Tubular Structures
This laboratory develops an analytical solution to predict the characteristics of compressive stress around dowel bars in jointed concrete pavement systems. With the deflection data generated from finite element analysis (FEA), the amplitude and distribution of compressive stress within the dowel slot are precisely predicted.
