In recent times, economic losses due to earthquakes have increased exponentially worldwide mainly due to the extensive development of dense urban areas. Therefore, seismic risk mitigation and reduction are receiving extensive funding for research and application worldwide. One of the innovations are the so-called Earthquake Early Warning Systems (EEWS), which are capable of sending warning alarms before the energetic seismic waves hit a city. Most of the development of these systems has been focused on improving the reliability of the seismic prediction and the suitability of warning times by using alarming thresholds for intensity measure parameters such as Peak Ground Acceleration (PGA). However, mid-rise and high-rise buildings have complex seismic behaviour depending on dynamic characteristics (e.g. fundamental period, lateral stiffness) which are not well correlated with the PGA. This study has developed Performance Prediction Equations (PPEs) for Engineering Demand Parameters (EDP), such as floor accelerations and inter-storey drifts, which are more suitable to assess the seismic performance of structures. Furthermore, real-time assessment of building response was done by including these equations in the EEWS framework. Finally, a simulation demonstrating the benefits of using the proposed EDP instead of the classical PGA has been carried out for an EEWS for the Campania Region using different building typologies and alarming thresholds.
