A computer model for predicting infilled frame behaviour

A computer model is developed for the structural analysis of masonry infilled frames. Structural interaction of the panel and its peripheral frame is considered. Various failure criteria are incorporated into the model and special elements are developed to account for masonry failure by cracking and crushing as well as to account for the complex interaction of frame and panel. Comparison of analytical findings with the results of 31 laboratory tests on steel and reinforced concrete infilled frames showed favourable correlation and verification of the computer model.Key words: masonry, infill, frame, steel, concrete, computer, model, testing, correlation, failure.
