Evaluation of the Design Procedures of the Linked Column Frame System and improving its Seismic Behavior using Double Linked Column Pattern

The linked column frame (LCF) as a seismic resistant system with the ductile behavior using shear fuse will reduce the damage to other members of the structure at different hazard levels. In this paper, the seismic behavior of the LCF systems designed by Shoaib and Malakoutian procedures has been ev...
