چکیده

Abstract


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.

نتیجه گیری

6. Conclusions


Four experimental campaigns are briefly presented. The first one shows the experience of in-situ tests of strengthened walls in an actual building, and demonstrates the efficiency of wrapping, but exposes the problem of sufficient connection of the strengthened wall to the rest of the structure. The second campaign deals with different materials and FRP layouts and shows the difficulties with the bond between a strong coating and the weak masonry wall if there is no wrapping. The third campaign explores the use of innovative flexible materials (polymers) as the matrix for the FRPs. Finally, in the fourth campaign, a full scale building model was strengthened using the experience of the first three campaigns, and tested in the laboratory. The results show that seismic behavior of masonry structures can be substantially improved with proper use of FRPs.
