Abstract As for structures with rubber bearings during earthquakes, some firstly damaged bearings and the other normal bearings form a typical spring-friction isolation system. Furthermore, a rough contact surface, due to the stochastic damage of bearing, and the around smooth contact surfaces form a convex distribution of friction coefficient. This paper attempts to analyze seismic responses of a spring-friction isolation system with a theoretically and linearly convex friction distribution, in which the friction coefficient gradually decreases with the distance from the center. The results show that such friction distribution inevitably increases the structural relative displacement and possibly enlarges the structural acceleration and residual displacement under earthquakes. The convex pattern of friction distribution should be avoided in practical engineering, since it reduces the seismic isolation efficiency.
