Linked Column Frame with 3 shear links

After the LCF with 5 shear links was tested, the sacrificial links were replaced by 3 links. This experiment followed the same procedure as before using hybrid simulation allowing for full scale study at the system level accounting for the uncertainties via experimental component and having the ability to model more conventional behavior through numerical simulation. The system overall had exhibited three distinct performance levels; linearly elastic, rapid return to occupancy where only the replaceable links would yield, and collapse prevention where the gravity beam components also become damaged. Experimental results indicate a viable system under seismic loading, offering a new ductile structural system with the ability to rapidly return to occupancy.
