Abstract

This paper presents the results of two series of experimental and analytical studies on the structural behavior of an innovative moment-resisting connection to concrete-filled circular hollow sections using blind bolts. The first part of the paper presents a large-scale T-stub connection with full instrumentation tested to failure in tension, and the second part presents a series of pullout tests to explore the anchorage behavior of cogged bars within concrete-filled steel tubes. The favorable strength and stiffness characteristics of this type of connection showed that it could be an alternative to conventional welded moment-resisting connections. A 3D finite-element (FE) model was develope..
