The performance of masonry buildings under wind loads - The influence of the global effect on component response

The following contribution focuses on the global behaviour of masonry structures subjected to wind loads. It describes the interaction between the structural elements and their influences on the global behaviour. Numerical models based on discrete / finite element approach of different scales have been built for a typical terraced house masonry building.
The models have been used to investigate the contribution of each shear wall to the overall capacity of the structure, and to determine the portion of each from vertical/horizontal loads. The results give an insight into the interaction between the deformation of the slab and the rocking of the shear walls. The different performances between the model with rigid foundation and the model with elastic foundation have been compared.
Models for strips of the building have been built with an intention to deal with in-plane behaviour separated from the influences of load distribution. A comparison of the results of the strip model with the results of the global model shows, that the strip model results are in safe side.
