A simple method is given for the design of earthquake resistant buildings using three-stage friction-grip elements. Predesign is done by static analysis and verification is performed by time-domain computation on a micro computer. Distribution functions are given for the frictional forces that assure uniform behaviour under various earthquakes. A seven storey office building is presented as example. Statistical variation of frictional forces is shown to be of minor importance to the uniform behaviour.
