Abstract. Results from the authors’ blind prediction of a recent shaking table test performed at the IZIIS´s Lab on a nearly full-scale RC frame building with masonry infills are presented. The specimen was subjected to ten unidirectional ground motions of increasing intensity, ranging from 0.05g to 1.2g. An overview of the experimental set up and testing procedure is presented. Details on the numerical model used for the blind prediction are provided. These include modeling of the RC members, infill panels (with and without openings), mass, damping and P-delta effects, among others. Finally, comparison is made between the experimental and predicted displacement time-histories, which were ranked second among ten international entries.
Keywords: blind prediction, infilled frame, reinforced concrete frame, nonlinear analysis.
