Reducing the in-plane effect of infill on steel moment frame

In this paper, four large-scale one-story steel moment-resisting frame specimens have been tested. The first specimen is a onestory steel moment-resisting frame without masonry infill walls. The second is similar to the first but with infill wall having full physical contact to the frame. The other two are non-structural infill walls. The first non-structural infill wall has a complete decoupling from the frame, while the second has a full contact at the top of the wall and separated from the columns. The results of this paper have shown that life safety performance level for non-structural infill wall having a complete decoupling from the frame has satisfied the allowable story drift. This was not the case for infill wall having full physical contact to the frame or nonstructural infill walls sepatared from two sides.
