Improving the seismic response of existing framed structures is a matter that has attracted several researchers and practitioners in the last few years. This paper presents a topology optimization strategy for such goal that is based on a transfer-matrix representation of the mapping between the base acceleration and the structural response. The general approach is framed in a frequency-based dynamic context but a quasi-static approximation is available as well that is shown to be quicker and still successful. Analytics of the approach are presented first, the key-point being the Singular Value Decomposition of the transfer matrix, followed by numerical applications that are simple enough to be tractable but capable to display the potentials of the proposed reinforcement strategy.
