Seismic strengthening of RC buildings using CFRP

Abstract

A full-scale RC frame with inadequate detailing in the beam-column joints was tested on a shake table as part of a European research project. After the initial tests which damaged the structure, the frame was strengthened using CFRP and further tests were carried out. In this paper, nonlinear time-history analyses of the bare and FRP-strengthened building are presented. Bond-slip and bond strength degradation models under cyclic loading were implemented to simulate deficient beam-column joints. Experimental data from the shake table tests were used to calibrate the analytical models. The numerical models are used to assess the efficiency of the CFRP intervention using a set of real earthquakes. It is shown that the CFRP strengthening resulted in substantial improvement of the seismic performance of the deficient building.
