1 the challenge of analytical modeling: case study of full scale shake table experiments on one-storey rc frames

 reliable prediction of the structural seismic behavior is one of the challenging issues which has a direct impact on the advancement of the knowledge, tools and methodologies for structural design and assessment. full scale seismic experiments are among the rare opportunities to test our capabilities on all these aspects. in this paper, two one-storey reinforced concrete frames with the same overall geometry but different reinforcement details (i.e. ductility levels) were modeled using opensees. the full scale 3d prototypes of the frames have been tested on lnec shaking table in lisbon, portugal using an earthquake ground motion with four intensity levels. the paper presents the experiences gained from the pre- and post-test modeling of the structures. the analytical roof displacement time history response is compared with those recorded during the tests. the results shows an acceptable agreement between the numerical and experimental values, which is improved by some calibrations after the actual test.
