Fracture Critical Members
For railway bridges, fracture critical members (FCM) are those members or components of members loaded in tension whose failure would be
Fracture Control
Fracture-critical members are treated in the AASHTO LRFD Specifications and in the AASHTO Guide Specifications for Fracture Critical Non-Redundant Steel Bridge
Forces in Frames Subjected to Lateral Loads
The design loads for wind and seismic effects are applied to structures in accordance with the guidelines in Arts. 9.2 to
Force Method (Method of Consistent Deflections)
For analysis of a statically indeterminate structure by the force method, the degree of indeterminacy (number of redundants) n should
Forces in Statically Determinate Trusses
A convenient method for determining the member forces in a truss is to isolate a portion of the truss. A
