Effects on buildings from blast induced vibrations – a numerical pre-study

Paper i proceeding, 2022

It is well known that blasting in rock may cause structural damage to nearby buildings.
There are differences among most countries regarding legislation with respect to blast induced vibrations.
Criticism has been raised against this unclear situation, and it is of importance to develop more reliable
predictions on ground and structural vibrations. The present work has its origin based on the features
within the Swedish Standard. These guidelines are related to distance and underground conditions,
contrary to many other national standards which are based on frequency measures. There is a desire to
update the Swedish Standard; either based on distance, frequency or some other measures. This pre-study
considers numerical studies (2D FEM) for modelling blasting effects. The aim is to illustrate how various
parameters (material, geometry, load) influence ground vibration phenomena as well as structural effects
above-ground.
