In steel bridges, fatigue is often a major problem limiting the load-carrying capacity and the residual Diaphragms and cross-bracings are vital elements which are used in many bridge types to ensure these transverse and torsional loads are more obvious in curved and skewed.

Trusses have been used in a similar way to beams in composite decks (Oresund Approach Spans), as arches (Sydney Harbour Bridge), as cantilevers (Forth Rail Bridge) or as stiffening girders to suspension bridges (Forth Road Bridge).
The fatigue life evaluation of in-service steel bridges should be conducted based on the performance of the bridge structure under actual live loads. This is because the assumptions made on service loads during the design stage usually do not provide sufficiently accurate File Size: KB.

The V-load method is evaluated by comparison to a more refined finite element analysis method developed for curved bridge units.
The finite element analysis is described in a companion report. This work is part of Research Project. In Korea, most of steel bridge have the shape of box type and have been mainly applied to curved section. However, there are some cases that I type girder were applied in curved bridges.
Such I type girder has structural disadvantage compared to box type due to torsional forces, and potential of damage by fatigue is considered to become higher as time goes by: 1. Focusing on steel bridges, fatigue is often a major problem limiting the load-carrying capacity and the residual life of existing structures.
The correct identification of fatigue-prone details in a bridge, along with well-planned inspection routines and successful strengthening and repair schedules, can guarantee the continuous and satisfactory performance of bridges during their service by: A combination of corrosion, lateral motion, bridge skew, and fatigue cracking caused the Mianus River Bridge to fail (Figure ) inkilling several people (Fisher et al., ; Gorlov, ).
Corrosion in this steel plate girder bridge led to geometric changes in the joint and generated unanticipated forces. • Horizontally curved bridges with or without skewed supports and with a maximum L/R greater than where L is the span length bearing to bearing along the centerline of the bridge and R is the radius of the centerline of the bridge cross-section.

Fatigue is among the most critical forms of damage potentially occurring in steel bridges, while accurate assessment or prediction of the fatigue damage status as well as the remaining fatigue life of steel bridges is still a challenging and unsolved issue.

Numerical simulation is a feasible method of studying such fatigue damage. In British standards, the finite element method (FEM) is recommended as a rigorous method for steel bridge fatigue analysis.

Fatigue Cracking in Welded Steel Bridges JOHN W. FISHER AND CRAIG C. MENZEMER A number of localized failures have developed in welded steel bridge components because of fatigue crack propagation, which in some instances has led to brittle fracture.
Increases in the number of trucks and allowable weights has led to a rapid accu File Size: 4MB. Crossframes in horizontally curved steel I-girder bridges are primary members. They must be designed for strength and fatigue. Curved girder analysis computer programs typically compute crossframe member forces only due to curvature effect; they do not calculate the crossframe forces due to wind and centrifugal forces.
Fatigue cracks initiated from various connection details are common problems in steel bridge structures. Extensive research has been performed in the past few decades and design/evaluation guidelines have been developed for bridge engineers.
