Abstract:
An experimental investigation is presented on the dynamic lateral load tests of four-story models of steel frames with reinforced concrete infills. Various factors, e.g., the provision of shear connectors between the frames and the infills together with the effect of openings in the infills, are examined in terms of the strength and stiffness of the models. The crack patterns and the modes of failure of the models are important features to be noted in relation to the dynamic behavior of infilled frames. The shear connectors played a vital role in improving the strength and stiffness of the infilled frames, whereas the presence of openings in the infills considerably reduced the capacity of the structures to withstand dynamic loading.
