| Popis: | A diverse range of masonry infill walls is frequently used for low and medium rise reinforced concrete residential and office buildings. Exterior and interior partitioning walls are usually regarded as non-structural elements, even though masonry infill panels alter the seismic behaviour of buildings. Under earthquake loadings, the influence of infill panels may significantly increase stresses developed in some structural elements of the building. Residential and office buildings that have ground floor commercial or parking spaces develop a particularly dangerous pattern, where soft storey mechanisms might lead to premature failures. This paper examines the structural behaviour of masonry infilled RC frames under in-plane loading. A numerical modelling approach is adopted. Infill masonry walls are modelled as equivalent single diagonal struts. This model depicts the general behaviour of a building adequately enough, even if it cannot accurately reproduce local effects resulting from the interaction between frames and infill panels. Nonlinear push-over analyses are carried out for a range of alternative configurations of an outer wall of a building. Bare frame and masonry infilled frame behaviour are compared and the influence of masonry types is assessed. Subsequently, the influence that the ground floor infill walls absence exerts on the failure pattern is analysed. Conclusions reflect the influence that masonry infills have on the behaviour of RC frames for in-plane lateral loads. |
