Abstract
The 78 m Arts Tower at the University of Sheffield has been refurbished during the period 2009–2011, with improvements that included replacement of facades and partitions. The structural changes have been reflected in changes in dynamic properties that have been tracked by a pair of roof-top mounted tri-axial seismometers. The response data have been analysed in real time and accessed by web-viewer, capable to show that natural frequencies have changed dramatically during and after the retrofit. The monitoring system has demonstrated significant variations in modal parameters at different response levels.
The information from the exercise has been used to validate performance predictions by the consulting engineers.
