This paper describes unidirectional shaking table tests on seismic pounding of a 3-D RC building structure. Two inputs were considered: a seismic accelerogram and a harmonic wave. The tested specimen is a one-and-a-half-story 2/5 scaled portion of a RC building structure consisting of waffle slabs and columns. The instrumentation consisted of strain gauges, displacement transducers, acoustic emission receivers, accelerometers and video recording cameras. The experiments are simulated with SeismoStruct by using linear elements with concentrated plasticity; pounding is described with a concentrated Kelvin-Voigt model. The initial after-test observations showed some damage in the columns.
