Abstract
The effectiveness of the traditional force-based (FB) design method based on the use of the acceleration response spectrum has inherent shortcomings due to uncertainties in the estimation of the lateral stiffness and natural periods in building structures. The narrow perception of seismic actions as inertia forces (or acceleration demands) has been broadened in this paper to embrace the concepts of both velocity (energy) demand and displacement demand. A structure is deemed to perform satisfactorily if any one of the criteria based on velocity, displacement or acceleration is satisfied. Consequently, structures can be scanned quickly using one of the criteria to identify those requiring a fo..
