Abstract
In this work, two steel framed-structures with slabs were tested. One frame was statically tested for the removal of edge-column and the other was dynamically tested for the sudden removal of edge-column, so that the displacement and strain responses of the structure during the column-removal process can be obtained. Moreover, based on the principle of energy conservation, the vertical displacements at the column-removal location in the two tests were compared. The maximum displacement of the structure for sudden column removal was 60% larger than that of the static case. The principle of energy conservation ignores the effects of strain rate and damping on the dynamic behavior of the structure. It is conservative and reasonable to establish the equivalent dynamic load-displacement curve by using the principle of energy conservation. Additionally, based on the verified finite element analysis, the effects of the location and number of edge-column removal on the collapse resistance of the structure were studied. It was found that the simultaneous failure of corner and edge columns had the most adverse effect on the structure.
