Abstract
Nine bolted glulam beam-to-column connections were tested to study their mechanical properties, seven of which were strengthened by self-tapping screws. Results show that glulam beam-to-column connections are easy to tear along wood texture, which can be prevented by the strengthening of self-tapping screws. When the edge/end distances of bolts are less than the limiting values of the 'Technical specification for structural glued laminated timber' (GB/T 50708-2012), the capacity and ductility are increased. The ultimate bearing capacities of joint specimens with 20 mm and 14 mm diameter bolts are improved by 112% and 81% respectively.
