Ground-Borne Vibration in Buildings: Industry and Academia Perspectives

Dr Giuseppe Sanitate: An overview of vibration engineering applications in the building industry with a focus on ground-borne vibration

Vibration engineering applications can be found in several aspects of building design: footfall excitation, machine-induced vibration, construction-induced vibration, and ground-borne vibration. This presentation will provide a brief overview of these aspects and discuss in more detail the design of base-isolated buildings against ground-borne vibration. A performance-based design framework is presented, which aims at simplifying the challenging task of predicting the level of vibration attenuation (i.e. the isolation performance) obtained by mounting the building on resilient elements (e.g. rubber bearing or springs).

Giuseppe Sanitate is a Vibration Engineer working at Ramboll UK. He has a background in Civil Engineering, Structural Engineering and Earthquake Engineering. He is passionate about building dynamics and wave propagation in soils and has a PhD in Engineering from the University of Cambridge.

Tisal Edirisinghe: Predicting the dynamic response of foundations and buildings near underground railways 

Ground-borne vibration is of particular concern in cities due to the close proximity of underground railway tunnels to buildings. Vibration generated at the wheel-rail interface propagates through the track and tunnel structures, and then through the ground into buildings, resulting in perceptible vibration and re-radiated noise, most noticeably within the frequency range from 25 to 250 Hz. Due to the complex nature of the problem, there is a lack of research that is focused on developing our physical understanding of the wave phenomena and parameters that govern the dynamic soil-structure interaction. This talk will highlight some of the main conclusions from recent numerical studies on the response of piled foundations and buildings. Metrics for evaluating a building's vibration performance are also proposed, which could be adopted to help guide design practices in the future.

Tisal Edirisinghe is a final-year PhD researcher working in the Dynamics and Vibration Group of the Department of Engineering, University of Cambridge. His research interests include structural dynamic problems, ground-borne vibration and noise, railway vibration, and computational modelling. He obtained his Masters in Mechanical Engineering from the University of Cambridge in 2018.
