摘要

New alternatives are presented for detailing columnrnstiffeners in steel moment resisting girder-to-columnrnconnections that avoid welding in the k-area. Theserndetails were evaluated using monotonically-loadedrnpull-plate experiments, cyclically-loaded cruciformrngirder-to-column connection experiments, and three-dimensionalrnnonlinear finite element analysis. Thernresults confirm that existing AISC design equationsrnfor local flange bending (LFB) and local webrnyielding (LWY) are reasonable and conservative forrnnon-seismic design applications and may bernconsidered for seismic design applications.rnHowever, improved design provisions for LFB andrnLWY are presented that correlate better with test datarnfrom this research and the literature. Revisions arernalso recommended for panel zone design provisions.rnThe results also indicate that the welded unreinforcedrnflange-welded web (WUF-W) prequalified momentrnconnection can perform well under cyclic loadingrnprovided that the weld metal used in the connectionrnhas a minimum notch-toughness; that unstiffenedrncolumns perform well in the connection region, bothrnfor monotonic and cyclic loading, if the columnrnsection is sufficiently large; and that the alternativernfillet-welded continuity plate and doubler platerndetails explored in this research all performed well.
