Abstract

Under large earthquakes, the first floor columns sustain severe damage and these damages may cause collapse in the first floor. To decrease the damage of the columns, free standing structures whose first floor columns are not fixed are a choice. The seismic response of the structure is greatly influenced by the kinematic friction at the base. This paper studies the kinematic friction between steel and mortar, which are widely used in construction. Two shaking table tests were conducted by putting a rigid structure or flexible structure on a mortar base. The test results showed that stick-slip phenomenon changed the kinematic friction greatly. A parametric study for a free standing structure subjected to ground motions showed that types of kinematic friction affected the sliding displacement, but it was not so influential to the damage of structures.
