Abstract
The results of pseudodynamic (PD) tests, those concerning stiff specimens
especially, may be seriously impaired by systematic errors. The paper deals
with the error analysis of PD seismic tests on relatively stiff half-size-scale
infilled frames, modelled as single-degree-of-freedom systems. Several performance
indices are reported and applied to a first group of experiments.
The nature and degree of the error inherent in the laboratory system is
deduced. A simple correction for that error is statistically identified and
used in the subsequent tests. The improvement is assessed by applying the
aforementioned indices again. It is shown that one can mitigate the error
by taking account of the stiffness deterioration of the specimens.
