“…This is located at an epicentral distance of 155.1 km, but only at 42.7 km from the fault, and presented a PGA of 0.269 g. Moreover, the importance of the distance to the ruptured fault plane can also be observed in other earthquakes, or through the results of stochastic simulations [44]. This type of comparison was also carried out by another author for Nepal, in the context of the Gorkha earthquake (Mw = 7.8) that occurred on 25 April 2015 [96]. This means that the distance to the fault plane rupture seems to be a better choice, regarding accuracy issues, when selecting a GMPE to deal with high-magnitude earthquake events.…”

This work summarises the strategy adopted in the European research project PERSISTAH. It aims to increase the resilience of the population, focusing on the existing primary schools in the Algarve (Portugal) and Huelva (Spain) regions. Software was developed to assess the seismic safety of these schools, considering different earthquake scenarios. Seismic retrofitting measures were studied and numerically tested. Some of them were also implemented in the retrofitting activities of two case study schools (one in each country). It was found that the adopted ground motion prediction equations (GMPEs) considerably affect the results obtained with the software, especially for offshore earthquake scenarios. Furthermore, the results show that the masonry buildings would be the most damaged school typologies for all the scenarios considered. Additionally, a set of guidelines was created to support the school community and the technicians related to the construction industry. The goal of these documents is to increase the seismic resilience of the population. Different activities were carried out to train schoolteachers in seismic safety based on the guidelines produced, obtaining positive feedback from them.

“…This method requires the zero-padded portion to obtain accurate velocity and displacement waveforms when integrating from zero. Consequently, it may need more analysis runtime for structural dynamic analysis [12].…”

In condition monitoring of structures, acceleration time histories are usually recorded due to ease of instrumentation. In cases where the information about a displacement time history is required, the acceleration data needs to be integrated to obtain the velocity and then the velocity needs to be integrated to obtain the displacements. However, the numerical integration of the acceleration data usually introduces an unrealistic drift component to the velocity as well as displacement. This paper presents an eigenfunction method to derive velocity and displacement time histories from a given acceleration time history. The paper analyzes displacements in two case studies using the numerical integration as well as the proposed eigenfunction method. It is concluded that the eigenfunction method is a viable approach to derive the displacement information from the acceleration data.
