Abstract

In this study, the seismic performance of SFRC pile cap using headed main bars in foundation beams was examined by a lateral loading test and an FEM analysis. A double strut model, involving the development of two struts in the pile cap, was identified as the stress transfer mechanism under lateral loading. The first strut to be formed connects the compressive parts at the opposite foundation beams end sections. The other strut to be formed connects the compressive part at the foundation beam end section to the head anchors of the foundation beam longitudinal bars of the beam end side.
