An integrated experimental-theoretical investigation was performed on the dowel behavior at high-strength reinforced concrete in the high-rise building. Results of an experimental study on the dowel action of beam longitudinal bars at beam-column interfaces in high-strength concrete(450 ~ 600kgf/cm<sup>2</sup>) frames are presented. The crack patterns and dowel load-deflection diagrams are presented for specimens with different sizes of dowel bars. Test results indicate that the stiffness and energy dissipation capacity of dowel bars deteriorate severely with repetition of inelastic load cycles.
