The pseudodynamic test method is a powerful procedure for seismic performance testing. However, the method has analytical limitations due to the discretisation of the structure and to the numerical integration procedures used. The control of many degrees of freedom, as in multi-storey frames or in structures with distributed masses, may lead to an impractical test arrangement and to an excessive reduction of the time step of the integration algorithm. In this study, a method in which a reduced number of degrees of freedom is controlled during the test is presented. The advantages of this approach are explored and practical guidelines concerning the minimum number of degrees of freedom to be controlled for different classes of structures are derived.
