Dr Nicky de Battista will introduce the Cambridge Centre for Smart Infrastructure and Construction and give a presentation on monitoring the progressive axial shortening of Principal Tower.
Principal Tower is a 50-storey reinforced concrete high-rise building being constructed in central London. The structural system and architectural layouts of the building presented the design engineers (WSP) and the contractors (Multiplex Construction and Carey's) with several challenges, one of which was how to measure and account for the time-dependent, differential axial shortening of the concrete columns and walls.
This presentation will showcase a novel monitoring system, which was developed by researchers at the Centre for Smart Infrastructure and Construction (CSIC) at Cambridge University, to continuously monitor the axial shortening of the building's vertical load-bearing members. The system consists of distributed fibre optic sensors which are embedded within the members and can be used to record the concrete shortening at every stage during and after construction, with unprecedented spatial and temporal density. This monitoring system has been used for the first time in Principal Tower. Some of the data measured during the construction of the Tower will be presented.
Dr Nicky de Battista is a researcher based in the Cambridge Centre for Smart Infrastructure and Construction.
