EARTHQUAKES, THE EFFECT OF DISTANCE AND LOCAL GROUND CONDITIONS ON THE GROUND MOTION CHARACTERISTICS

JORDSKJELV, VIRKNING AV AVSTAND OG LOKALE GRUNNFORHOLD PAA RYSTELSENES EGENSKAPER

The Scandinavian peninsula is considered a seismically quiet zone, yet every year a series of measurable vibrations are set off by earth crust movements. Several larger earthquakes have also occurred and could have caused a great deal of damage, had they been near a high density built-up area. In the design of structures able to withstand the effects of earthquakes and other types of vibrations, the magnitude of the forces, the durability and the wave lengths are the factors of greatest importance to the resulting damage. These factors vary with the properties of the zone which sets off the earthquake, with the distance and the geology between the zone and the structure, with the ground conditions in the vicinity of the structure and with its dynamic properties. The paper considers especially the newer analytical methods which have been developed to determine how the movements will vary with distance and local ground conditions. Some of the results may be of interest for other dynamic problems in geotechnics. /Author/TRRL/
