Strengthening of MRF RC frames located in seismic areas with BRB and FRP

This paper presents the structural analysis of a RC frame GLD according to 50 years old Romanian standards. The design of the RC frame is followed by the structural analysis of the same frame strengthened by means of two methods. The first strengthening method is using a dissipative system represented by a BRB system applied in the middle spans of the frame as an inverted V system, pinned at the ends. The second method of strengthening is the confining of the columns, from the first two stories, by means of FRP techniques. In the first step the two methods are applied and analyzed separately on the frame, then a combination of them is applied and analysed.
