Abstract
This report treats an experimental investigation of gravity load design steel frames i.e. steel frames with semi-rigid connections, infilled with unreinforced masonry walls and subjected to slowly applied cyclic lateral loads. An investigation of the mechanical properties of the materials used in constructing the masonry infill walls is included. Various geometrical configurations of the frame and the infill walls, and different material types of the masonry walls are considered. Based on the results, a hysteresis model for infilled frames is formulated and discussed. All parameters in the model have physical meaning and are calibrated with experimental data.
