Seismic Behavior and Design of Cast-in-Place Anchors

Abstract eng:
Cast-in-place anchors are used to connect steel members (i.e., girders and columns) with concrete (i.e., walls and foundations). The behavior of anchor connections directly affects the behavior of a structure in the event of an earthquake. A thorough understanding of the seismic behavior of cast-in-place anchors/headed studs is necessary to ensure safe member connections and structural performance in such events. This paper summarizes existing experimental data and analytical studies on the behavior of cast-in-place anchors/headed studs under cyclic loading (including cyclic tension, shear, and combined tension-shear in the literature. Design equations from several building codes around the world have been reviewed and compared. The presented information will provide an overview of the modern day understanding of seismic anchor design and areas of seismic anchor design that are being addressed by an ongoing research project.
