Abstract

In the present paper numerical analysis of damaged masonry structures using finite element method is presented. Retrofitting of those structures using technology DC90 is outlined to. Experimental results of testing of dampers in relevant institutes are described. Besides that, tests on vibroplatform for various masonry structures are presented. Examples of retrofitting of damaged structures in Kolubara region are explained in detail.

Keywords: damage, earthquake, retrofitting, dampers, testing
