Abstract: Earthquake
simulator tests of a 1/6-scale nine-story reinforced concrete frame-wall model
are described in the paper. The test results and associated numerical simulation
are summarized and discussed. Based on the test data, a relationship between
maximum inter-story drift and damage state is established. Equations of
variation of structural characteristics (natural frequency and equivalent
stiffness) with overall drifts are derived by data fitting, which can be used to
estimate structural damage state if structural characteristics can be measured.
A comparison of the analytical and experimental results show that both the
commonly used equivalent beam and fiber element models can simulate the
nonlinear seismic response of structures very well. Finally, conclusions
associated with seismic design and damage evaluation of RC structures are
presented.
