A wide section of the guideline focuses on the brittle failure mechanisms. In particular, according to experiences gained from examining the performances of RC structures after seismic events, a wide section focuses on the most common brittle collapse mechanisms resulting from shear failure of partially confined beam-column joints (i.e. exterior or comer joints on the perimeter of the stmcture in some cases, where frames are only in one of the plan directions, they could be also interior). The typical joint failures observed in the L Aquila post earthquake are described and a local strengthening procedure by means of FRP, steel jacketing or CAM technique is discussed.
