Seismic Force-Resisting System is defined as, the part of the structural system that has been considered in the design to provide the required resistance to the seismic effects. In the Seismic Design Codes, the structural systems consisting of structural elements (column, beam, shearwall, brace) and Modification Coefficients of these structural seismic force-resisting systems are defined. Modification Coefficients vary according to the structural system type and ductility level. Response modification coefficients are defined in Seismic design Codes.
