The diagonal application of Carbon Fiber-Reinforced Polymer fabrics on hollow clay tile infill walls has been qualified as an efficient rehabilitation method for deficient reinforced concrete frames. However, majority of the experimental studies were conducted on 1/3-scaled RC frames and the effect of specimen scaling has not been questioned. In the current study, the results of an experimental campaign on 1/2-scaled RC frames are presented. Test specimens are grouped in two series having two different aspect ratios. In each series, there are two RC frames having hollow clay tile infill walls with/without CFRP reinforcement. The results of 1/2-scaled specimens are compared with the experimental results obtained from 1/3-scaled frames. In addition, the numerical model which were developed by the authors for 1/3scaled frames are employed for modeling 1/2-scaled specimens and the results were assessed by comparing with the test results.
