It is very important to establish a visible damage index for quick damage estimation of steel structures. In the reconnaissance of the 2011 Tohoku earthquake, many cracks on the concrete foundation around the exposed steel column-base were observed. Cyclic loading tests focusing on a crack pattern and its width on concrete foundation were conducted to investigate the relationship between structural performances and the damage indices. The major findings obtained from the test are summarized as follows: (1) the maximum story drift angle, column-base rotation, and elongation of the anchor bolts can be estimated by crack width between concrete foundation and cover mortar; (2) lateral deformation due to the concrete edge failure can be estimated by the width of diagonal cracks growing from anchor bolts in the compressive side to the foundation beam.
