Abstract: This study examined seismic behavior under long-duration ground motion in flexural-dominated reinforced concrete bridge columns designed per modern seismic design codes. Two column specimens with identical design parameters ...

Abstract: This paper proposes a simplified finite-element analysis (FEA) method to analyze the axial compression behavior of rectangular concrete columns confined by interlocking multispiral reinforcements. The proposed method uses ...

Abstract: The seismic behavior of the proposed precast segmental unbonded posttensioned concrete bridge columns for use in regions of high seismicity was investigated experimentally. Posttensioning tendons were placed in the hollow ...
