To investigate their adequacy as energy dissipating elements during earthquakes, this paper reports on cyclic inelastic tests executed to determine the maximum strength and ductility of four concrete-filled circular steel piers joined to a foundation detail proposed to develop the full composite strength at the base of these columns. Column diameters considered were 324 and 406 mm, with D/t rat...

This study is dedicated to the development of a generalized confinement model applicable circular concrete columns confined by FRP full and partial arrangements. To simulate axial stress versus strain curve, new strength proposed addressing relation pressure during loading , whose calibration was based on an extensive set test results. By combining theoretical basis experimental observations, i...
