A New Technique

The possibility of strengthening existing R/C structures with a new technique based on the application of a High Performance Fiber Reinforced Concrete jacket is investigated herein, with the aim of studying the effectiveness of this technique for seismic retrofitting. The results of a beam-column joint full scale test simulating the behavior of existing beam-column joints are presented. The specimen have been subjected first to static loads and after to cyclic actions with increasing amplitude, up to failure. The tests demonstrated that, with the application of a HPFRC jacket, it was possible to remarkably increase the bearing capacity of the columns reaching also an adequate level of ductility, and the resistance of the beam column joints, with very little visible damage, thanks to the tensile strength contribution of HPFRC.
