The practice of blind bolting connections to structural hollow sections : A review

Abstract     [Full Text]
    Due to aesthetic, economic, and structural performance, the use of structural hollowrnsections as columns in both continuous moment resisting and nominally pinned construction is attractive.rnConnecting the beams to these sections is somewhat problematic as there is no access to the interior ofrnthe section to allow for the tightening of a standard bolt. Therefore, bolts that may be tightened fromrnone side, i.e., blind bolts, have been developed to facilitate the use of site bolting for this arrangement.rnThis paper critically reviews available information concerning blind bolting technology, especially thernperformance of fasteners in shear, tension, and moment resisting connections. Also provided is anrnexplanation of the way in which the results have been incorporated into design guidance covering thernparticular case of nominally pinned connections. For moment resisting connections, it is concluded thatrnwhilst the principle has been adequately demonstrated, sufficient data are currently not available tornpermit the provision of authoritative design guidance. In addition, inherent flexibilities in the connectionsrnmean that performance equivalent to full strength and rigid is unlikely to be achievable: a semicontinuousrnapproach to frame design will therefore be necessary.
