Tests on a welded moment-resisting connection to join precast beams and columns are reported. If precast moment-resisting frames are to be used in areas susceptible to seismic disturbances, it is necessary that the joint and members behave in a ductile manner. The joint detail adopted in these tests incorporates improvements on a similar, previously tested joint type. Both exterior-joint specimens (a single beam intersecting a column on one side only) and interior-joint specimens (beams intersecting a column on opposite faces) were tested under reverse loading. Experimental results show that this joint detail can withstand large ductility demands.
