- Abstract
- An accurate and practical testing technique to study the seismic performance of multistory infilled frames is formulated. This technique is based on the pseudo-dynamic method which can provide an acceptable approximation of the dynamic performance of structures under the influence of real earthquake excitation. The pseudo-dynamic experimental techniques is outlined and applied for testing a two-bay, two-story gravity load designed steel frame infilled with unreinforced concrete block masonry walls. It was shown that careful implementation of the pseudo-dynamic technique may lead to an excellent control over the experimental error propagation, even for stiff structures such as infilled frames.
