A seismic design approach was presented where the design procedure attempts to create RC (reinforced concrete). Buildings with a specified limited objective under a specified level of seismic intensity. The limited objective may be directly defined as some damage states of a certain weak storey. The famous Park-Ang damage model, constant ductility inelastic response spectra and the conventional seismic design method were combined to determine families of structures whose initial strength and stiffness characteristics will ensure that the desired limited damage performance objective for each seismic level is, as closely as possible, achieved. Furthermore, the applicability of the parameter γh for storey response of multiple degrees-of-freedom structures was analyzed, and the corresponding equation was established. Finally, a design example shows that the design approach is feasible and accurate.
