RC beam strengthening using precast RC plate bonding technique
Abstract
The behaviour of RC beams strengthened with precast RC plates of rectangular and U cross-section is studied in the paper. An experimental investigation was conducted to assess effectiveness of strengthening with precast plates. The investigation was supported with the 2-D nonlinear finite element analysis (NLFEA). The NLFEA results showed a good level of correlation with test results. The proposed technique is considered to be a good alternative to RC jacketing and the technique is practical, economical and reliable for buildings or bridges with a greater number sisof similar beams.
