Vibration monitoring in old residential buildings subject to traffic v
Vibration monitoring in old residential buildings subject to traffic v
(OP)
Traffic calming speed humps are being installed in an ancient High Street, with resulting potential vibration damage to adjacent buildings with minimum foundations. Is there advice available on a monitoring regime which might indicate extent and frequency of vibration damage to buildings constructed in traditional brickwork with lime mortar??

We need to find out first if there is a genuine problem, to allay fears of local frontages.

I have also used the blastmates and they can be made to work very well.

The condition you have given will result in very low frequency and probably low amplitude. These are usually not a big problem for buildings; however, checking to get the actual magnitude is better.
Some departments of transportation have limit data that you might reference. The the Florida Department of Transportation....they have a procedure to monitor vibrations during construction with PPV limits.

TRL Report 235 also is helpful, so I am closing down this enquiry, thank you for your help.

Although vibrations monitoring may provide a general indication of the possibility of damage, you just don't know until you observe the behaviour of the building.
I wouldn't hang my hat on vibrations monitoring alone. A complete review of the existing condition should be performed. In addition, crack monitors and surveying benchmarks should be installed and monitored to determine if there is any movement.
The best way to determine if there is damage is to continually monitor the structures. If you start to see signs of damage, then you need to do something.

Sounds like you have a great opportunity for a research project! An older building, or five, to be removed could be monitored for distress with increasing PPV and some guidelines could be established. I'll bet the historic boards and transportation department would give some funding.

You may want to check out the German standard DIN 4150.

He specifically referenced the DIN 4150 (part 3--1999) and BS 7385 (part 2--1993) standards, but went into detail with the Dutch SBR-2002 standard. The SBR defines 3 classes of structures (incl one for historic bldgs) and 3 types of vibrations (incidental, repetitive, continuous)and goes on to provide recommended allowable measured vibrations for each case, dependent on vibr frequency (and several correction factors).
Also, Caltrans has set some limits, including 2.0 mm/s for continuous vibrations and historical structures.
