Numerical dynamic tests of masonry-infilled RC frames

Several numerical dynamic tests of two-storey masonry-infilled reinforced concrete frames were performed by adopted numerical models. Bare frames, fully masonry-infilled frames and masonry-infilled frames with openings, with variants of strong or weak concrete frames and masonry, were studied. Uniform harmonic base excitations and base excitations by three real scaled earthquakes were applied. Among other, it is concluded that cross-sectional dimensions of frame, rigidity of masonry, openings in the masonry and type of dynamic base excitation have significant influence on behaviour of masonry-infilled reinforced concrete frames. Finally, some recommendations for practical application are given.

► Several numerical dynamic tests of two-storey masonry-infilled RC frames were performed.
► Bare frames, fully and partially masonry-infilled frames were studied.
► Harmonic base excitation and three real scaled earthquakes were applied.
► Special developed material models for masonry and reinforced concrete were used.
► Rigidity of infilled frame and type of earthquake significantly effects obtained results.
