The World

<p>As the expectations of populations all around the world continue to increase in relation to the resilience of their bridges and buildings to hazards such as seismic events, the need for appropriate solutions – which can be applied both to new structures and to existing ones – grows accordingly. A wide range of solutions is available, such as shock absorbers and shock transmission units which can be used to dampen or optimally transmit forces that would otherwise damage a structure, and seismic isolators which can protect buildings and bridges from destructive ground motions. Expansion joints can be equipped with features that protect a bridge, at its key movement nodes, from damage due to larger-than-expected movements, and structural health monitoring (SHM) can be used to enable hazards to be identified and to provide immediate notification of any event that might make a structure unsafe. Various such methods of enhancing resilience of structures to seismic and other hazards are described.</p>

Automated Decision Making

The integration of internet of things, artificial intelligence, and blockchain enabled the monitoring of structural health with unattended and automated means. Remote monitoring mandates intelligent automated decision-making capability, which is still absent in present solutions. The proposed solution in this chapter contemplates the architecture of smart sensors, customized for individual structures, to regulate the monitoring of structural health through stress, strain, and bolted joints looseness. Long range sensors are deployed for transmitting the messages a longer distance than existing techniques. From the simulated results, different sensors record the monitoring information and transmit to the blockchain platform in terms of pressure points, temperature, pre-tension force, and the architecture deems the criticality of transactions. Blockchain platform will also be responsible for storage and accessibility of information from a decentralized medium, automation, and security.
