Abstract

The performance of a new proposed steel connection against seismic loading and progressive collapse was experimentally and numerically investigated in this paper. The seismic performance included interstory drift angle and flexural strength evaluated in accordance with 2010 AISC Seismic Provisions whereas progressive collapse assessment was based on satisfaction of the acceptance criteria by rotational capacities of the connection provided in UFC 4-023-03 guideline. The results confirmed that the new proposed connection was capable of achieving adequate rotational capacity and developing the full inelastic capacity of the connecting beam. In addition, an excellent cyclic behavior was demonstrated by proposed connection which enhance interstory drift angle. Based on the results the proposed connection has adequate intensity and ductility to classify it as full-strength and ductile connection.
