What are typical design displacements?
In high seismic zones such San Francisco, Tokyo and Istanbul the isolator displacements are up to 30 inches (750 mm). For structures located further from faults or on better soil the isolator displacements are up to 20 inches (500mm). In low seismic zones such as the eastern United States, movements are in the range of 2 to 6 inches (50 to 150 mm). DIS has tested isolators to 47 inches of lateral displacement and provides isolators for all seismic zones worldwide.
