Hi!
What is the right damage criteria for buildings placed on hard rock. I know the standars say about 70 mm/s, but does anyone have knowlegde and experience around this?
I would like to get as much data as poosible from projects where vibration damage are caused by blasting in hard rock areas. Data like spesific charge, distanse, type of rock, type of damage in buildings etc.
Thanks a lot!

Hi,
did you get any information about damage criteria ?
If you have any data about blasting that made damage on the building, plese contact me.I have worked on some blasting projects where 10 cm/s didnt made any damage.

Hi,
I donn't know what's kind of standards you mentioned. 70mm/s is too high. In my memory, it is about 20mm/s for building.

Damage criteria can not be chosen without understanding the vibration situation (type of structure, building and foundation situation), resonance frequency of building and/or ground etc.
I suggest that you review different vibration guidlines, which have been reviewed on the following web page:

You have to consider the limits for structural vibrations, not for ground vibrations. I would like to advise you to read the following paper: Svinkin, M.R. "Regulations of Construction Vibrations". Deep Foundation Institute, Conference Proceedings, 2006, pp. 557-571.
If you have a problem to find this paper, please let me know.

There shoul be a certain blasting criteria based on the structures and the standard rules have to be followed for damage criteria.
