Abstract: This paper experimentally investigates the seismic behavior of tie bar stiffened round-ended concrete-filled steel tube columns. A total of 16 specimens were tested. The test parameters included the axial load ratio, bending ...

Abstract: Based on the damage ratio strength theory, a dimensionless damage ratio strength criterion for fiber-reinforced concrete (FRC) under true triaxial stress states was established under the assumption of small strains. Based ...
