PROTECTING BUILDINGS AGAINST GROUND-BORNE VIBRATION
The principal of protection of buildings against earthquakes is to design so that the lowest natural frequency should be above the highest frequency of significant excitation by an earthquake. For protection against traffic vibration, the building is mounted on springs so that its dominant natural frequencies are less than the frequencies of the excitation. The latter technique can also be used against earthquake vibration. Properly designed buildings in earthquake zones are constructed to withstand the full horizontal acceleration load produced by a design earthquake. This method has the disadvantage that occupants and fittings in the building also experience the full force of the motion. It has been found that natural rubber is the most suitable material for mounting of buildings. The cost and engineering of a typical building is illustrated by the example of a building designed to the Mexico Code of Practice. A large number of buildings have been protected against traffic induced vibrators by being mounted on springs.
