谢菲尔德大学78米的艺术塔在2009-2011年期间进行了翻新，包括更换立面和隔板。结构变化反映在动态特性的变化中，通过长期加速度监测和振动测试相结合来跟踪动态特性的变化，以识别局部和全局振动模式。将建筑物的整体水平面模态与有限元模型模拟和实时自动操作模态分析相关联，以表征结构变化对摇摆和扭转水平振动模态的影响。此外，地板振动测试链接到有限元模拟确定的贡献的“非结构分区”的地板动态性能。用现代轻质模板取代重型砌体隔墙导致刚度降低，但摇摆振动适用性没有明显变化，楼板性能仍然令人满意。
The 78 m Arts Tower at the University of Sheffield was refurbished during the period 2009–2011, with improvements that included replacement of façades and partitions. The structural changes were reflected in changes in dynamic properties that were tracked by a combination of long-term acceleration monitoring and vibration tests to identify local and global vibration modes. The global horizontal plane modes of the building were correlated with finite element model simulations and real-time automated operational modal analysis to characterize the effects of the structural changes on horizontal vibration modes in sway and torsion. In addition, floor vibration tests linked to the finite element simulations identified the contribution of ‘non-structural partitions’ on the floor dynamic performance. Replacement of heavy masonry partitions with modern lightweight forms has resulted in reduction of stiffness, yet there is no obvious change in sway vibration serviceability and floor performance remains satisfactory.
