Lateral Behavior of Precast Segmental UHPC Bridge Columns

The concept of an equivalent plastic-hinge model was used to evaluate the lateral behavior of precast segmental ultra-high-performance concrete (UHPC) bridge columns. The columns consist of precast UHPC segments that were integrated by unbonded post-tensioning (PT) tendons and complemented with energy dissipation (ED) bars.
