Abstract:
The use of UHPC is currently expanding worldwide from bridge deck joints and connections to full components and larger applications. To improve structural design of UHPC members for different applications in bridge or buildings, a better understanding of the damage mechanism and sections capacity is needed. With focus on columns, and as a result of the enhanced mechanical characteristics of UHPC and high compressive strength, more slender sections are expected relative to conventional reinforced concrete. The objective of this presentation is to provide an overview of the structural response of UHPC columns with varying reinforcement details and slenderness effects. The current ACI 318 procedure for slender columns and second-order moment analysis is assessed and design recommendations are provided for UHPC axial and slender columns.
