Summary In the paper, the response of a typical 3‐D masonry building subject to dynamic disturbance is considered, with the purpose to identify control strategies able to mitigate the effects of the excitation. The structure is made of vertical planar elements (the walls) firmly jointed at the wall crosses and horizontally connected by rigid floors. The structural control of the building is realized through the introduction of a suitable dissipative action, which is operated through active, semi‐active, or even passive devices. The control action is ruled by suitable algorithms that are optimally designed with the purpose to optimize the balance between the reduction of the oscillations of the floors, and consequently of the ductility demand to the walls on one side, and the intensity of the control force on the other side. The system behaves in dependency of the single‐wall shear displacement in‐plane constitutive law that can be identified on the basis of the no‐tension model with shear friction strain modes. The behaviour of the whole is ruled by the relevant non‐linear history‐dependent equations. The control strategy is developed for non‐linear systems and then specialized and tested for the presented application to seismic protection of masonry buildings.
