Seismic-Resistant Bridge Columns with Ultrahigh

AbstractThe flexural capacity of a well-designed RC column deteriorates under extreme ground motion as a result of crushing of the core concrete and buckling of the longitudinal bars in the plastic hinge regions. Thus, it is important to minimize damage at the plastic hinge region to develop high-performance bridge columns. A column that uses ultrahigh-performance concrete (UHPC) segments at
