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: In most structural steels, the critical plane-strain stress-intensity factor, KIc , which represents the inherent ability of the material to resist crack propagation, increases with increasing ...

Abstract: The useful life of highly constrained welded structures subjected to cyclic loads often depends on the crack-propagation behavior of the material. Thus, to predict the service life of many ...

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 ...

Abstract: Increasing use of high-strength steels in pressure-vessel design has resulted from emphasis on decreasing the weight of pressure vessels for certain applications. To demonstrate the suitability ...

Abstract: Many of the fractures observed in welded moment connections after the Northridge earthquake propagated through the column flange either as a divot or completely through the column section. The effect, if any, of through-thickness ...

Abstract: A new steel orthotropic deck was installed on the Bronx–Whitestone Bridge (BWB) between 2005 and 2006. In May 2007, longitudinal cracks were found by visual inspections underneath the deck plate in the rib-to-deck welds ...
