Building structures using Precast Reinforced Concrete Wall Panels (PRCWP) are widely used in Romania. An important disadvantage of these buildings is the functional rigidity of the interior space due to the dense distribution of the load bearing walls. Cut-out openings are often required to facilitate direct access from outside or between adjacent apartments. This paper presents a part of research program regarding the effectiveness of using the Externally Bonded Carbon Fiber Reinforced Polymer (CFRP-EBR) composites as seismic retrofitting solution for PRCWPs weakened by cut-out openings. The discussion was focused on the strengthening strategies adopted for both narrow and wide door openings.
