AbstractA 1:200-scale, seven-level lumped-mass model with three degrees of freedom per floor has been designed and constructed to simulate the dynamic behaviour of a 57-storey office building in Toronto. A model design procedure is described that allows for coupled modes produced by the effect of the offset of the centre of stiffness from the centre of mass. Measurements of the model's dynamic response indicate a good simulation of the first few fundamental modes of the building. Preliminary wind-tunnel results show that torsional response has an important effect on the measured displacements and accelerations of the stucture, demonstrating that dynamic response can be underestimated if torsion is ignored.
