Abstract

Dynamic interference effects can be devided into four categories:

  • buffeting excitation

  • interference to vortex shedding

  • interference galopping

  • wake galloping

The buffeting excitation is connected with shelter effects and both effects have to be taken into account for the resulting peak wind load of a downstream building. In unfavourable position the increase of this peak load may be up to 50%. From wind tunnel tests “buffeting factors BF” which are based on the stochastic wind load concept have been developed for different situations of adjacent buildings.

The interference effects to vortex shedding and galloping are presented for circular cylinders and the mechanism of these phenomenae are explained. Some characteristic values for the estimation of the instability point are given.
