Abstract
Ground-borne vibrations from roadway traffic are a common source of disturbance in urban areas. These vibrations are often due to poor road conditions combined with heavy vehicle movements near the receiving structure. Mitigation of vibration disturbances in existing structures usually requires a combination of added mass, added stiffness, and/or added damping to limit vibrations to acceptable levels. The suitability and feasibility of solutions will largely depend on site conditions, performance, and cost.
This paper presents a case study on control of traffic-induced ground motion disturbances in a historic residential structure. The building was previously occupied by commercial space but was known to have lively floors subjected to perceptible levels of motion induced by vehicle movements on the adjacent roadway. The desire of the owners to convert the commercial space to residential use raised concerns regarding impacts of traffic on comfort in the home. To assist with the renovation, the authors were engaged to investigate the problem and develop solutions for control. Site testing was completed to quantify existing vibration levels and structural dynamic properties. This was followed by an investigation of solutions including structural retrofits, passive dampers, and active control. Ultimately the owner proceeded with structural retrofits and following the renovation there was opportunity to complete performance measurements for verification of the solution.
