摘要
Here, in order to study effects of strong and weak connections of corridor on wind-induced vibration responses of twin-tower super high-rise buildings, firstly, simplified mathematical models for wind-induced vibration response analysis of twin-tower connected super high-rise buildings with strong and weak connections were established, respectively. Secondly, based on the engineering example (two-tower heights are 268 m and 210.2 m, respectively), natural vibration characteristics of structures with two connection modes were analyzed. Finally, wind-induced vibration responses of the structure with two connection forms were estimated according to results from wind tunnel tests of synchronous multi-point pressure measurements of the buildings under 24 wind directions. The results showed that the strong connection form can reduce peak acceleration responses of two towers under most wind directions, and the reduction effect of wind-induced vibration acceleration response on lower tower is better than that on higher tower; the strong connection form can also reduce peak displacement responses of higher tower under almost all wind directions, and displacement responses of lower tower can be dominated by higher tower which cause peak displacements of two towers in the same direction; the study results can provide a reference for wind-resistant design of connected super high-rise buildings. © 2021, Editorial Office of Journal of Vibration and Shock.
