The present study experimentally simulates and analyzes the damage of bearings in steel large roofs that was observed after the 2011 off the Pacific coast of Tohoku Earthquake. In this study, cyclic shear force is given to three models of slide bearings and four models of semi-fixed bearings. In the slide bearing tests, mobility is the first interest and in the semi-fixed bearing tests, damage and crush of base mortar are focused and the shear strength is evaluated according to the AIJ recommendation. In the Part1, the overview of the experiment and the behavior of slide bearings is described.
