Estimation of hysteretic soil damping from laboratory measurements including strain accumulation
Løvholt, Finn; Johansson, Jörgen (NGI Rapport;20110087-01-R, Research report, 2014-05-12)The periodic forces due to wind, surface waves and swells on offshore installations such as offshore wind turbines lead to cyclic motion of the soil foundation. The damping properties of soils account for a part of the ... -
Evaluation train induced ground vibration boom with Vibtrain
Håård, A.; Johansson, Jörgen; Viking, K.; Larsson, S. (Chapter, 2024)The Swedish Transport Administration is planning new high-speed railway lines that will connect Stockholm, Gothenburg, and Malmö, with operating speeds from 250 to 320 km/h. However, at such high speeds in soft soil areas, ... -

Vibration induced damage due to construction work – Effect of vibrations on slope stability
Johansson, Jörgen (NGI-rapport;20170774-D4.3, Research report, 2019-08-29)A landslide-triggered tsunami caused extensive material damage at Statland, Norway in 2014. Other landslides in Sweden and US have also been triggered by man-made vibrations. To understand better how vibrations from vibratory ...
