Abstract: This paper presents the approaching used for the organization of a 106 m tall office structure, which will be the full-length in Bucharest. The event at severe seismic state implies the process of a favorable energy dissolution chemical action and this can be checked only by nonlinear dynamic analysis. The activity at wind actions is more complex than for ordinary buildings and comprises a dynamic response. Conventional (code) reasoning was considered not enough hi-fi and wind tunnel tests were performed, on static and elastic models in the wind tunnel facility of the Technical University of Civil Engineering. The 3D energizing nonlinear abstract thought and the wind dig tests allowed a safer organization of the commercial enterprise structure.
