Seismic Performance Evaluation of Steel Moment Resisting Frames with WUF‐B Connections
The purpose of this study is to evaluate the seismic performance of the moment resisting steel frames having Welded Unreinforced Flange‐Bolted web (WUF‐B) connections. The connections are designed and detailed in compliance with FEMA 350 recommended seismic design criteria. To conduct the seismic performance evaluation this study developed an analytical model for the pre‐ and post‐Northridge connections based on test results. Three different frames are considered which have three‐, nine‐ and twenty‐story. Incremental Dynamic Analysis (IDA is conducted to estimate limit state capacities The performance of the frames having either pre‐ or post‐Northridge connections is compared with the corresponding frame with ductile connections which do not experience connection fracture. The analytical results showed that buildings with post‐Northridge WUF‐B connections provide superior strength and interstory drift ratio capacity than buildings with pre‐Northridge WUF‐B connections.
