Experimental Study on the Seismic Performance of Brick-Infilled Steel Frames with and without Retrofit

摘要

Experimental results are presented for three infill frame sub-assemblages. The specimens were constructed from bolted steel frames, infilled with clay brick masonry, and testedin-plane under quasi-static cyclic loading. Each specimen was either retrofitted or, following initial testing, repaired with a thin ferrocement overlay. Results showed that all specimens performed well up to interstory drifts of approximately 1.5%. The inclusion of ferrocement gave a marginal improvement in energy dissipation. Conclusions are drawn on the efficacy of ordinary brick or rehabilitated infills as seismic resisting elements.
