Evaluation of soil-building resonance effect in the urban area of the city of Matera (Italy)

摘要: Abstract This study discusses the effect of buildings vibrations in urban field context local seismic response studies order to evaluate possible occurrence double resonance effects during strong-motions. The aim is recognise interaction between near surface geology and all overlying area city Matera (southern Italy). Single station ambient noise measurements (230) were performed on main lythologies (134) principal building typologies (96). Soil allowed estimating frequencies relative amplitudes soil fundamental peaks as well first vibrational frequency buildings. period-height linear relationship, derived by experimental results, made it for Matera's Having also estimated at each point was thus obtain a soil-building map elastic domain. represents an important case because vibration most quite close those foundation soils. About 21% show high probability effect, about 63% are characterised medium level, while 16% zero or very low level. proposed approach makes identify areas these different probabilities levels.
