Blind Bolting W‐Shape Beams to HSS Columns

Response and component characterisation of semi-rigid connections to tubular columns under axial loads

“…It is evident from the figure that plasticity took place at the column face in the area in direct contact with the beam flange. It is also evident from the figure that large plastic punching 9 deformations accumulated in the column face in the case of specimens with angle/beam widths smaller than the column face width (i.e Specimens C1 and C2). Significant flexural deformations also occurred in the horizontal (column) angle leg in these cases.…”

“…The costs associated with the construction, inspection and maintenance of fully welded details have motivated the development of other connection alternatives such as the flowdrill process [5][6][7] and special bolts with sleeves designed to expand inside the tube [8][9][10]. A simpler blind-bolt design is that proposed by Lindapter International [11] through the development of the Hollobolt.…”

Behaviour of beam-to-tubular column angle connections under shear loads

“…The cost and maintenance implications associated with welding have prompted the development of semi-rigid open beam-to-tubular column connection alternatives such as the flowdrill process [6][7] and special bolts with sleeves designed to expand inside the tube [8][9]. A simpler blind-bolt design is the Hollo-bolt, proposed by Lindapter International [10].…”

Behaviour of combined channel/angle connections to tubular columns under monotonic and cyclic loading

“…Another alternative for bolted connections between open beams and tubular members is that offered by specially designed blind-bolts equipped with sleeves that expand inside the tube [19,[22][23][24][25][26][27]. Korol et al [26] performed tests on five end-plate bolted beam to column connection assemblies using Blind Oversized Mechanical Bolts (BOM) and High Strength blind-bolts (HSBB) developed by Huck International Inc [27].…”

“…Korol et al [26] performed tests on five end-plate bolted beam to column connection assemblies using Blind Oversized Mechanical Bolts (BOM) and High Strength blind-bolts (HSBB) developed by Huck International Inc [27]. It was shown that the behaviour of open beam-to-tubular column connections using HSBB was similar to that using conventional bolts whereas a connection employing BOM bolts did not achieve equivalent levels of strength.…”
