Capacity Detailing of Members to Ensure Elastic Behavior

The objective of this task is to develop seismic design and capacity detailing recommendations for all portions of bridge piers that do not participate as primary energy dissipation elements. particular emphasis is given to the design requirements of cap beams and their connections of multi-column bridge pier bents. By prestressing the joints it is possible to ensure the joints remain elastic. Prestress enhances the bond and anchorage of the longitudinal column bars and also minimizes or avoids diagonal shear cracking in the joints.
