Project Name/Title/Acronym:Tall buildings experience wind induced motion ***********
Funding Body: ************
Project Timeframe: **********
Project Description:
- Tall buildings experience wind induced motion which can result in serviceability and habitability issues associated with occupant discomfort and nausea. The construction of modular residential towers in which volumetric modules are assembled around a reinforced concrete core offers significant economic, environmental and safety advantages. However, these structures can be particularly susceptible to wind induced accelerations due to the tall slender form of the core and the small and uncertain contribution of the modules to global lateral stiffness and damping. This project investigation the acceleration response of modular towers using field measurements and computational modelling, and evaluates potential mitigation measures including the use of tuned liquid dampers.
- Research on this topic directly addresses the SDG of sustainable cities and communities as it seeks to extend technology use to the provision of urban residential accommodation using novel construction techniques. It contributes to the TrinityHaus research pillar of Healthy People and Places as its results will reduce nausea symptoms experienced by the occupants of tall buildings during strong wind events, and to the Healthy Planet research pillar as it will also lead to structures with smaller carbon footprints.
