Abstract :
This paper introduces a new numerical method for the analysis of infilled steel frames with
hollow clay blocks. This approach is based on the brittle cracking model of ABAQUS. The
results of the in-plane calibration analyses obtained with four experimental tests are presented
and discussed. The first test was a bare steel frame used as a control specimen. The second
was similar to the first one, but with an infill wall in contact with the frame. In the third
specimen, the infill wall was completely separated from the frame. The infill wall of the fourth
specimen had full contact at the top of the infill wall to the frame and separated from the
columns. In the second part of the study, improved versions of the third and fourth specimens
have been investigated numerically. Results reveal that the brittle cracking model can be
useful in assessing the behavior of masonry infill walls. Furthermore, it can be concluded that
the separation of infill walls from the steel frames is quite helpful in reducing the
inappropriate effects of infill walls on the overall behavior of buildings.
