A comparison of current non-linear analytical methods to the results of a series of pseudo-dynamic tests performed on a full-scale reinforced concrete frame building is presented. The structure studied was damaged by a series of pseudo-dynamic seismic tests, repaired using carbon fibre reinforced polymer (CFRP) jackets, and then subjected to another series of pseudo-dynamic tests. The earthquake motion used was an artificially generated accelerogram based on the Eurocode 8 design spectrum. The test structure consisted of two parallel, equally dimensioned, four-story, three-bay frames joined by a reinforced concrete slab. One frame was designed as a high ductility class frame in a high seismic zone according to Eurocode 8 rules. The second frame was designed to resist the same level of earthquake using a displacement based design procedure. The non-linear structural analysis programme IDARC 5 was used to perform full non-linear time history analyses of both the bare and CFRP repaired frame. A capacity spectrum analysis according to ATC 40 guidelines was also performed for both the bare and repaired frames. The results of the pseudo-dynamic tests and the analytical analyses are presented and compared.
