Modelling strategies for horizontally loaded infill masonry / Modellierungsansätze für horizontal beanspruchtes Ausfachungsmauerwerk

The realistic modelling of seismically loaded infill masonry is a complicated task due to the complex interaction of the infill with the surrounding frame. Practical approaches, that take into consideration the non-linear behaviour of the infill and the frame, are especially lacking at the moment. Within the framework of the European project INSYSME (Innovative Systems for Earthquake Resistant Masonry Enclosures in R.C. Buildings [1]), the behaviour of infill masonry in reinforced concrete frames is being investigated experimentally to derive different strategies for the modelling of infill masonry. In addition, systems for the improvement of the seismic behaviour will be developed. In the following, some initial results of the different modelling strategies are presented.
