Description
Summary:This paper presents a seismic safety system composed of Raspberry Shake Sensors (RS4D), as cost-effective seismographs, alongside Elastomeric Isolation Systems for a seismic protection method. The system considers RS4D sensors to collect data used to identify earthquake prone regions where isolation systems are installed accordingly, and to Earthquake Early Warning (EEW) systems. A case study in Morocco is proposed, where the suggested system is tested for its accuracy and efficiency. The findings indicate a 5.7 % variability in RS4D sensitivity, remaining within a 4 % margin of the Osopcal (OSOP)-specified nominal sensitivity. Furthermore, retrofitting with elastomeric bearings resulted in a significant reduction, ranging from 0.5 to 0.3, in structural acceleration during seismic activity. A cost analysis and design requirements for the suggested system are also covered. This suggested scheme holds the promise of emerging as a pioneering seismic safety initiative in Morocco, reducing the risk of casualties and structural damages.
