Description: A precast substructure may consist of multiple columns with a cap or a single pier. Precast caps may be installed on precast or cast-in-place columns and foundations. Regardless, superstructure-to-cap, cap-to-column, and column-to-footing connection details must effectively resist applied loads to achieve good long-term performance. But just how do these connection details differ for non-seismic versus seismic loading? And how can performance-based design be included in the mix? This presentation will provide an overview of the differences in design requirements and details for connections in non-seismic and seismic regions.
