Vibration Control Of Downtown Toronto High-Rise Development
MetadataShow full item record
In this industry-academia collaboration, a multi-platform hybrid numerical simulation was performed to assess the effectiveness of a tuned liquid damper (TLD) to be installed in a high-rise condominium located in Downtown Toronto. The structure was modeled using OpenSees, while the nonlinear TLD model was developed in MATLAB. A dynamic analysis was performed using statistically-generated dynamic wind loads. It was determined that the TLD improved the performance of the structure (storey acceleration, roof drift) for various levels of wind loading, improving the comfort of the residents of the building. Minimal benefit was observed for reducing base shear as well as storey shear demands on the structure.
