Abstract

Acceptable probabilities of collapse for seismically isolated buildings could be achieved by an appropriate isolator displacement capacity. This paper investigates the effects of the over-stroke capacity, in addition with the displacement capacity of the isolation system, on the seismic response of a structure isolated with double concave curved surface slider isolators. The case study is a moment resisting steel framed building in which the isolation system assumes different displacement limits. Results from nonlinear static analysis and nonlinear time history analysis demonstrate that over-stroke displacement of the isolators may significantly increase the safety factor in case of earthquakes bigger than the design ones, without drawing on the plastic resources of the structure and changing the construction costs.
