Four experimental campaigns performed at ZAG over almost a decade and dealing with strengthening of masonry using FRPs are briefly presented. The campaigns show in-situ tests on strengthened walls in an actual building, the cyclic shear laboratory tests where different materials and FRP layouts were explored, use of innovative flexible materials instead of mortar or epoxy, and finally the test of a full scale building model where all aspects of strengthening a building using FRPs are investigated.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 2312807The fundamentals of earthquake resistant consstruction in seismic protection are presented. In the paper, typical earthquake damage to buildings ia analyzed and basic information to improve the deficiencies is provided.

F.11 Development of a new service
COBISS.SI-ID: 2263911Experimental and analytical studies of the in uence of the buckling in the longitudinal reinforcement on the seismic response of existing concrete bridge columns were performed. Based on the previous tests of typical I-shaped bridge piers the design of new cyclic tests of rectangular columns was performed. The impact of the inappropriate seismic detailing and the in uence of the concrete cover on the drift and load-carrying capacity as well as on the buckling of bars was analysed. The experimental tests of the strengthened RC columns were also performed. At first, the efficiency of strengthening of the typcal I-shape bridge pier with substandard reinforcement was verified by means of CFRP wrap. It was concluded, that due to the unfavourable aspect ratio of the section anges the conventional strengthening is rather inefective. To improve the behaviour, columns were jacketed with pre-stressed CFRP fibres. In this way, the deformation capacity of columns was increased for more than 70 %.
