This paper presents an overview of the development of fatigue design provisions and detailing for steel bridge structures. The historical performance of welded steel bridges in the USA is reviewed with focus on fatigue cracking at cover plate and similar attachment details, as well as distortion induced cracking at web gaps. The role of materials including modern high performance steels (HPS) is reviewed. Variable amplitude loading is also examined and compared with current design of steel bridges for fatigue resistance. Also examined are methods to improve and retrofit fatigue sensitive details, including modern post-weld enhancement by ultrasonic impact treatment (UIT). Orthotropic steel decks are reviewed based on the results of two full-scale prototype laboratory fatigue tests which identified the complex behaviour that occurs at fatigue sensitive details and were verified by field measurements on field installations. The merits of thin epoxy concrete wearing surfaces is examined in terms of the critical role the deck plate thickness has on the epoxy concrete fatigue resistance and durability. The orthotropic deck is the only bridge deck system likely to provide a 100 year life when the deck plate thickness equals or exceeds 16 mm.

“…Available to the designers were the results of laboratory fatigue tests of a full-scale prototype and an as-built orthotropic steel deck for the Williamsburg Bridge rehabilitation (Kaczinski et al 1997, Tsakopoulos andFisher 1999), and field measurements on the south roadway decks after installation of the replacement orthotropic deck panels (Connor and Fisher 2001). The designers also had information from measurements on a prototype orthotropic deck panel that was installed and monitored on the suspended portion of the Triborough Bridge (Baker/ Ammann and Whitney 2001).…”

“…The refined design solution (using 2.3 6 HS15) resulted in the use of a deep diaphragm cutout geometry and internal rib wall stiffeners at each supporting floorbeam diaphragm (in place of 'bulkhead' plates as used in other decks (Kaczinski et al 1997, Tsakopoulos and Fisher 1999, Fanjiang et al 2004. The rib-to-diaphragm connections were specified to be complete-penetration groove welds with back-to-back reinforcement fillet welds along the entire length of the connection, similar to those used in other decks (Kaczinski et al 1997, Tsakopoulos andFisher 1999). Intermediate diaphragms were used to provide additional transverse stiffness to the deck system between floorbeams.…”

A significant portion of the current rehabilitation of the Bronx -Whitestone Bridge includes replacement of the roadway decking on the suspended span with closed-rib, steel orthotropic deck panels. Prior to the final design and production of the replacement panels, a full-scale laboratory fatigue test of a prototype panel was conducted at Lehigh University. The panel incorporated a diaphragm cutout and welded rib-to-diaphragm connection detail that was improved and refined with the aid of finite element models and experience gained from research conducted on orthotropic deck panels in the 1990s. Evaluations were made of the behavior and fatigue resistance of the orthotropic deck system and connections. Static and dynamic tests provided information on the two types of diaphragm plate splices and two types of bolted rib splices, determined the effectiveness of the rib wall stiffeners, and permitted a verification of a finite element model.

“…In Severn Bridge the transverse crossbeam cut-through the longitudinal ribs and there were several cracks generated in crossbeam to longitudinal rib welds. Then the transverse crossbeam turn into disconnected and cope holes are leaved in the crossbeam to longitudinal rib afterwards [5]. At the same time, the full penetration welds are widespread used in U-ribs to deck slabs weld instead of overlay welding, and the joints of vertical ribs of web to deck slabs were canceled [6,7].…”

Abstract. Four kinds of fatigue cracks are found in a suspension bridge with orthotropic steel deck. Finite element analysis was conducted to investigate the reason of fatigue cracks originated from the cope hole in the transverse crossbeams. The stresses surround the cope holes in the crossbeam are calculated under vehicle loads which are imposed on scheduled positions on the bridge deck. Then the relationship between the peak stresses surround cope hole and the loading position is acquired. There are 2 areas have the effects of stress concentration surround a cope hole, which are named area-A and area-B. The calculation results indicate that the peak stress in area-A is greater than the allowed fatigue stress-range under 2 million cyclic loads, and the actual position of fatigue crack detected in the bridge is coincide with the position of area-A.
