An optimal design problem formulation of elastic plastic frames under different combinationsof fixed and seismic loads is presented. The optimal structure must behave elastically for the fixedloads, shakedown for serviceability conditions and prevent instantaneous collapse for fixed and highseismic loads. P-Delta effects and element buckling are considered. An appropriate modal technique isutilized. The design variables can have components in a continuous field or, alternatively, in chosendiscrete sets or, yet, both kind of variables can be present. The design problem is formulated on theground of a statical approach. The applications are related to steel frames.
