Blind test prediction of an infilled RC building with OpenSees

Over the last years the seismic behaviour of infilled reinforced concrete (RC) structures have been focus of innumerous experimental and numerical studies. A big effort is being made by the scientific community with the aim of increase the knowledge regarding the seismic response of these type of structures and improve the numerical modelling accuracy to predict their expected behaviour. In 2015, a blind prediction contest was organized by the Faculty of Civil Engineering Osijek with main goal of invite the technical and scientific community to predict the nonlinear seismic behaviour of a 1:2.5 scaled 3D building struc- ture. The three-storey infilled RC structure was subjected to ten incremental earthquake se- quence on a shake table test. The blind numerical analyses were performed knowing only the specimen geometry, reinforcement detailing, material characteristics and the actual ground motions recorded during the testing. In this context and, in view of the author’s participa- tion success, the present paper mainly aims at presenting the key aspects of the adopted nu- merical methodology (and related difficulties) which proved to yield good results, while also providing some insight regarding key problems in numerical simulations of infilled RC structures seismic behaviour.
