Abstract
Full-scale fracture tests were completed determining that mechanically-fastened steel built-up axially-loaded tension members are resistant to running fracture when a single component suddenly fractures. This characteristic of built-up member is referred to as Cross-Boundary Fracture Resistance (CBFR). A comprehensive finite element model-based parametric study was also performed investigating the post-fracture load redistribution behavior of multi-component built-up members. Simplified closed-form solutions were developed for engineering analysis of built-up members to evaluate for internal member redundancy and estimate safe inspection intervals that are based on the fatigue life of the member in the assumed faulted condition.
