Seismic Performance of Concrete-Filled Steel Tube to Concrete Pile-Cap Connections
This study investigates the seismic behavior of the connection between concrete-filled steel tube piles and concrete pile caps. This connection is an important component of an accelerated bridge construction technique, which involves driving steel piles to a finished elevation just below the design deck level, forming a pile cap around the ends of the driven piles, reinforcing this cap, and then filling both the piles and formwork with concrete. This cap will then serve as the deck support system. In this research, a total of six connection specimens with various details were tested under lateral loads until failure while monitoring applied loads and lateral displacements. All of the specimens achieved the desired moment capacity, and all but one experienced a typical progression of damage in the concrete cap. This progression initiated with crushing of the concrete (interior and exterior), was followed by yielding of the longitudinal reinforcement, and concluded with yielding of the transverse reinforcement and the formation of diagonal cracks extending from the embedded pile to the edge of the cap. Based on the results of this and a previous investigation, an initial design methodology is proposed.
