Static friction coefficient is increased depends on the waiting time. We confirmed this by horizontal loading experiment of building using elastic sliding bearings. In order to confirm the influence on the earthquake response, we developed a program with a friction model considering the static friction coefficient, and we conducted the seismic response analysis of the target building. As a result, at level 1, the maximum layer shear force response increased and the maximum displacement response sometimes increased. At level 2, the maximum layer shear force response was sometimes the same or increased, but the maximum displacement response sometimes increased.
