Project description
An underground ‘shock absorber’ for building clusters
Significant work has been done to increase the elasticity and resilience of buildings to earthquakes via structural engineering. In contrast, the vibrating barrier (ViBa) concept is a large-scale oscillating mass-spring-damper unit placed underground and tuned to decrease the motion of nearby structures without contacting them via structure–soil–structure interaction. However, it requires a building-sized vibrating mass, a barrier to practical applicability. An inerter, a device like a shock absorber, could be a solution. With the support of the Marie Skłodowska-Curie Actions programme, the VIBRATIONCLEAR project aims to develop a concept for an inerter-based ViBa (I-ViBa) via 2D and 3D numerical finite element simulations considering multiple I-ViBA and a cluster of building structures.
Objective
Earthquakes are one of the deadliest and costliest natural hazards. In Europe, earthquakes have been responsible for more than 200,000 deaths and damage worth at least 250 billion euros during the 20th century. In Italy alone, more than 400 destructive earthquakes have been documented. In more recent history, the Central Italy earthquake in 2016 killed 297 people and caused damage worth at least 4 billion euros.
VIBRATIONCLEAR proposes the use of inerter-based vibrating barrier (I-ViBA) for earthquake protection of a cluster of building structures. The I-ViBA is unique because unlike any other currently available earthquake protection technologies, the I-ViBA is buried in the ground and tuned to protect surrounding structures without being directly in contact to them through a structure-soil-structure interaction (SSSI) mechanism. The I-ViBA can be a solution for a low-cost seismic protection technology for existing buildings as one I-ViBA can be designed to protect many surrounded structures, something that has never been explored before. Aiming to address the apparent gap, this VIBRATIONCLEAR project sets two key objectives: (a) propose a novel I-ViBA and its optimisation method; and (b) perform 2D and 3D numerical finite element simulations considering a more realistic environment (multiple I-ViBA with a cluster of building structures). Using both analytical and numerical methods, the I-ViBA will be accurately designed, modelled and simulated using finite element software with various types of earthquake ground motions.
With the support of my supervisor (Prof Marco Domaneschi) at the Politecnico di Torino, the Fellowship will train me in earthquake engineering and structural dynamics and act as a pilot for my own ERC Starting Grant on seismic protection technology. Ultimately, the project seeks to provide low-cost seismic protection technology for buildings to protect people from earthquakes.
