Blind Bolting WShape Beams to HSS Columns

Connecting a Wshape beam to a hollow steel section (HSS) column using conventional bolts is difficult due to a lack of access inside the hollow section column to tighten the nut. Field welding the connection remains the common practice. The objective of this work is to propose a bolted moment connection for rectangular hollow steel columns using highstrength blind bolts, and to evaluate such a connection in terms of its performance and its …
