Abstract: Fracture of unreinforced welded moment frame connections subjected to simulated seismic loads was caused by the initiation of fatigue cracks and their propagation to critical size. The fatigue cracks initiated at the ...

Abstract: Full-scale welded steel moment-resisting frame (WSMF) connections have been tested to failure at the University of Michigan and at Lehigh University. The tests were conducted at ambient temperature and under a simulated ...
