In this paper, among numerous different types of energy-absorbing devices, effect of viscoelastic damping on an interesting type of semi-rigid steel framing connection which is commonly used in Iran (including in seismic zone) has been investigated. Analytical investigations of the use of VE damper in civil engineering structures, show that the response of buildings due to strong earthquakes can be reduced significantly.

On the basis of extensive analytical and experimental investigations, some theoretical issues associated with the application of viscoelastic dampers to two different groups of common building structures in Iran, 1)hinge steel braced frames, 2) semi-rigid "Khorjinee" steel braced frames, for seismic performance enhancement are considered. It is first shown that the seismic response of a structure in two groups can be significantly improved with added damper.
