Innovative Seismic Isolation of Masonry Infills in Steel Frames using Cellular Materials at the Frame-Infill Interface
An innovative concept is proposed to isolate – at low and moderate story drifts – infill panels from the surrounding steel frame, using thin layers of cellular materials. The concept is verified experimentally through testing of fully infilled frames under in-plane cyclic loading. A simple analytical model is developed and implemented in OpenSees; the model is in good agreement with test results. It is concluded that the proposed technique has a high potential in reducing infill-frame interactions – hence damage of the infills – up to moderate drifts, whereas full interaction is still in place when drifts are large.
