Capacity Assessment of Gld Rc Frames Strengthened with Frp

Many gravity load designed (GLD) reinforced concrete (RC) frames are nowadays located in seismic areas. Different strengthening methodologies have been proposed in the past; an innovative technique based on the use of composites was proposed and validated by an experimental program developed at University of Missouri-Rolla. A theoretical approach for the assessment of the subassemblage capacity is herein proposed; the analysis of each component is carried out in order to find out which of them controls the strength of the connection. Theoretical outcomes are then compared with experimental results. Some remarks on the reliability of such approach are made and aspects to be further investigated are highlighted.
