<p>EACS 2016 Paper No. 111</p><p>Hybrid Simulation has been introduced to
simulate the seismic response of civil structures. The hybrid model of
the emulated system combines numerical and physical subdomains and its dynamic
response to a realistic excitation is simulated using a numerical time-stepping
response history analysis. In the current practice, lumped parameters
structural topologies such as shear type frames or inverted pendulum
characterize the physical subdomain and the design of the testing setup is
straightforward. Although hybrid simulation has been extensively exploited for
testing concrete and steel structures, in the authors' knowledge, there
is still a paucity of scientific publications devoted to masonry
applications. This is in contrast to the inherent uncertainty carried by
masonry failure mechanisms, which hinders any attempt of
implementing predictive numerical models. From this perspective, this
paper summarizes our recent research achievements aimed at extending hybrid
simulation to distributed parameter specimens, such as masonry walls, using the
minimum number of actuators. The great potential of reduction bases in
driving the substructuring process has been shown in a previous work and
here is enhanced to floating physical subdomains.</p>
