Distortion‐induced fatigue cracking is a concern for many aging steel bridges in the United
States. Human visual inspections to characterize fatigue cracks have many drawbacks …

This study presents a novel approach to detect damage in steel frames using a hybrid
network of piezoelectric strain and acceleration sensors. A numerical study has been …

Distortion-induced fatigue cracking is a primary maintenance and structural safety concern
in steel bridges built prior to the 1980s in the United States. Manual, hands-on inspections …

Distortion-induced fatigue cracks represent the majority of fatigue cracks in steel bridges in
the United States. Currently, bridge owners, such as the state departments of transportation …

Reinforced concrete beam bridges are usually retrofitted by a steel plate or FRP. However,
these two methods tend to result in disadvantages, eg, construction complexity and …

This paper reports full-scale fatigue tests, conducted to explore the distortion-induced fatigue
behavior of vertical stiffener web gaps in steel girder bridges, considering parameters such …

Distortion-induced fatigue damage at crossframe-to girder connections affects many steel
bridges built before the mid-1980s. This type of damage is associated with a prevalent …

For some long span cable supported bridges, the longitudinal diaphragms in main girder are
designed as steel truss to reduce structural self-weight. However, unanticipated fatigue …

Prior to the mid 1980's, bridge girders were often constructed with a gap between the end of
the connection plate and the flange in tension. This practice was stopped due to early …

To clarify the differences in the retarding effects by employing the steel and Fe-SMA sheet
reinforcements, both fatigue tests and finite element (FE) analysis were conducted in the …
