- Abstract
- Finite element analyses (FEA) have been used to accurately predict the behavior of the structural members. The
accuracy of the analysis results can be verified by comparing with test results. In FEA, the perfect geometry of a member is
often assumed. However, such assumption may lead to overestimation of actual member responses. This study proposed a
method considering geometric imperfections in FEA of WUF-W connections using the modal superpositions of buckling
analysis results. The best combination of scale factors was determined to best match the limitation on geometric imperfection
specified for W-section in ASTM A6/A6M. To verify the accuracy of the analysis results, the measured cyclic curves of tested
WUF-W connection specimens were simulated with FEA considering the initial geometric imperfection. It was observed that
the cyclic curves of WUF connection specimens obtained from FEA matched the their measured cyclic curves.
