PUSH-OVER NON LINEAR ANALYSIS OF INFILLED FRAMES:REALISTIC F E MODELS OF PANELS AND CONTACT
A finite element based modelling technique that enables the representation of the masonry infills in an analytical environment suitable for use in the assessment of low engineered masonry infilled reinforced concrete frame (LE-MIRCF) buildings has been developed. The mezo-modelling approach adopted for the masonry infills was implemented in a non-linear finite element environment. Fibre elements are used to represent the reinforced concrete members and a spring element for the interface between these and the masonry. The approach has been used to explore the effects of imposing different masonry infill distributions throughout a typical internal frame of a five storey LE-MIRCF structure which was analysed in the inelastic range, and its performance assessed. It is shown that the provision of masonry infills is not always detrimental nor always beneficial, but depends on the particular infill configuration, thereby justifying the approach used.
