DAMAGE ASSESSMENT OF MASONRY INFILLED FRAMES

There are many different parameters that affect the behavior of masonry-infilled reinforced concrete frames under earthquake loadings and it is difficult to predict. Selection of the parameters, that have the greatest impact on the response system, was carried out on the EDIF database of 113 one- storey one- bay infilled frame tests processed by statistical sensitivity analysis. Those parameters were height to length ratio, longitudinal reinforcement ratio of column and compressive strengths of concrete and masonry infill. A simplified and reliable analytical model, based on the equivalent diagonal and validated on different experimental tests, has been adopted for extensive studies on seismic vulnerability of infilled frame buildings. We investigated the seismic response and the influence of the masonry infills on the global structural response in terms of inter-storey drift ratio and damage states by incremental dynamic analysis. Results are presented in order to determine the relationship between infill’s type and damage state for low-rise infilled framed buildings.
