Traffic-induced ground motion and vibrations - Grunf - 09-08-2010

Dear members,

Does anybody possesses some kind of numerical/ tabular data (record) of the traffic-induced ground acceleration to share? I'm not looking for something specific - any kind of (tabular) data are welcome.



What I'm trying to say in a caricature way:

i.e. I have a picture of the traffic-induced ground acc. in verbatim looking like this:

but I don't have numerical record of it looking like this or similar:

(this is part of earthquake record written in .txt document)

So I need any kind of numerical record of the traffic-induced ground acceleration along (if possible) with its info (vehicle, ground layers, etc.)

You can send me data using e-mail:

Like most vibration problems, traffic vibrations can be characterized by a source- path receiver scenario.

Vibration amplitudes and the predominant frequencies are influenced significantly by the soil type and stratification. The lower the stiffness and damping of the soil, the higher the vibration. For impact loads, ground vibrations are highest at the natural frequencies of the site. At these frequencies, the soil, like any structural system, offers the least resistance and hence the greatest response to loads. For soils, the natural frequencies depend on stiffness and stratification.
