Evaluation Model for the 2nd Generation Wind-Excited Benchmark Building

Abstract eng:
The first generation wind-excited benchmark building was introduced to assess performance of control algorithms and devices suppressing uncoupled sway modes of vibration. The second generation wind-excited benchmark building, on the other hand, incorporates complex lateral-torsional motions which are typical of a significant number of modern tall buildings. A series of wind tunnel pressure tests were conducted to determine translational and torsional wind forces acting on the benchmark building. A finite element model was also constructed and mass, damping and stiffness matrices were subsequently formulated as an evaluation model for numerical analysis. The evaluation model is further simplified to a state reduced-order system (ROS) using the state order reduction method. The formulation details and methodology are presented in this paper.
