Sažetak
This paper presents results of a part of the Croatian research project "Seismic design of infilled frames". Within this part we have investigated the influence of different types and positions of opening in masonry infill, with and without tie-columns surrounding them, on the seismic response of R/C frames. Ten equal single R/C frames, designed and constructed according to Eurocode 2 and Eurocode 8, were built in a scale 1:2.5 and infilled with masonry walls. They were tested under constant vertical and a sequence of lateral load reversals till the infill failure (IDR =1%). The results showed that strength and stiffness properties were only slightly affected by opening position and type. Presence of the opening lowered energy dissipation capacity of the system. Without tie-columns an opening caused the infill subdivision and its sequenced failure mechanism. Tie-columns affected the infill’s mechanism of failure, ductility, equalized the behaviour and prevented its out-of-plane failure.
