Los terremotos se encuentran entre los desastres naturales que han producido históricamente mayores daños y pérdidas de vidas humanas. La capacidad destructiva de un terremoto depende de su magnitud, la vulnerabilidad de las construcciones y la capacidad de recuperación de la población. Por tanto, para minimizar sus consecuencias, se debe...

Existing RC framed buildings lack significant ductility, especially when they have been built with pre-code criteria. Improving their ductile capacity can help to prevent them from the brittle collapse mechanism and to reduce the seismic damage expected. This paper aims to investigate the enhancement of the ductile response behaviour of RC...

Existing reinforced concrete (RC) structures might not comply with current seismic codes due to their aseismic design and construction date. By seismically retrofitting them, it is possible to improve their seismic performance to resist the expected seismic loads. However, selecting the best solution is challenging since social and...

Seismic vulnerability and loss analyses of buildings are usually estimated under the fixed-based condition, omitting the soil-structure interaction (SSI) effects. However, according to the literature and the seismic damage due to past events, mid-to high-rise buildings located on soft soils can present a worse seismic performance. This...

The seismic safety of heritage buildings may be affected by the interaction between the soil, the foundation and the structure, which is usually neglected in conventional seismic assessments. These factors are particularly important in the case of slender constructions, such as masonry towers, over soft strata. Hence, this work deals with the...

The equivalent frame (EF) idealisation of masonry structures is widely used in engineering structures. Despite its simplifications, reliable numerical models can be produced to calculate the seismic behaviour of unreinforced masonry (URM) buildings. Different EF modelling approaches have been implemented in commercial software specifically...

A high percentage of reinforced concrete (RC) buildings in Portugal were designed and built before the introduction of modern seismic codes. This research aims to assess the seismic capacity and vulnerability of RC buildings in the city of Lisbon. For that purpose, nonlinear static procedures have been used and fragility curves have...

Soil-structure interaction (SSI) effects are usually omitted in the seismic vulnerability analyses of buildings. However, it has been proved that they might notably affect their seismic performance. In fact, European seismic codes establish that they should be included in the analyses of certain structures: with considerable second order (p-Δ)...

This manuscript discusses some preliminary results on the structural and the seismic performance of the Mosque-Cathedral of Cordoba, a UNESCO World Heritage. The area is characterized by a moderate seismic hazard. The building was built from the 8th to the 16th century and it has undergone several transformations. Owing to the complexity of the...

A project named PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese) is being developed. It aims to cooperatively assess and improve the seismic vulnerability of primary schools in the Algarve (Portugal) and Huelva (Spain). A large number of schools have to be analysed. In order to determine...

This paper aims to analyse the ductility of existing buildings to evaluate its influence in their 14 seismic performance. This has been achieved through the retrospective analysis of an existing 15 building in accordance with current seismic codes. This study has revealed the lack of guidance 16 in the NCSE02 and the EC8 regarding the...

A project named PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese) is being developed. It aims to cooperatively assess the seismic vulnerability of primary schools of the Algarve (Portugal) and Huelva (Spain). Primary school buildings have been selected due to their low adult/child ratio...

Previous research has indicated that many European buildings are vulnerable to moderate-magnitude earthquakes. For example, during the L´Aquila (Italia, Mw 6.3, 2009) and Lorca (Spain, Mw 5.9, 2011) earthquakes, many old buildings were severely damaged and some of them collapsed. In specific, significant damage has been found in several school...

El presente Ciclo de Innovación y Mejora en el Aula (CIMA) se aplica a la asignatura "Mecánica del Suelo y Cimentaciones (MSC)", impartida en el tercer curso del grado en Fundamentos de la Arquitectura (Plan 2012) de la Universidad de Sevilla. Según el Plan de Estudios, a esta asignatura se le asignan 6 créditos y se imparte durante el segundo...

The Iberian Peninsula is close to the Eurasia-Africa plate boundary resulting in a considerable seismic hazard. In fact, the southwestern Iberian Peninsula is affected by far away earthquakes of long-return period with large-very large magnitude. A project named PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de...

The seismic retrofitting of reinforced concrete (RC) buildings has been widely analysed. Most of the solutions proposed are focused on the building's structure improvement. However, the effects of ground-improvement techniques combined with the building's structure-improvement techniques have not been usually analysed. Therefore, this paper...

The present book aims to present the work developed in the European research project PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese), which has been developed cooperatively by the University of Seville (Spain) and the University of the Algarve (Portugal). This research project focuses...

The computational burden needed to perform a fragility analysis of structures can be excessive and beyond the capability of regular computing systems. In this work, a Neural Network (NN) implementation is presented to make fragility analyses attainable. Neural Networks allow finding solutions to complex problems at a fraction of the...

Most seismic vulnerability analyses do not consider the Soil-Structure Interaction (SSI). However, it has been proved that SSI does not equally affect all types of structures and all types of soils. The analysis of the state of the art reveals that SSI especially affects the performance of mid/high-rise buildings under soft/inelastic soil...

Capacity curves obtained from nonlinear static analyses are widely used to perform seismic assessments of structures as an alternative to dynamic analysis. This paper presents a novel 'en masse' method to assess the seismic vulnerability of urban areas swiftly and with the accuracy of mechanical methods. At the core of this methodology is the...

El presente libro tiene como objetivo la presentación del trabajo desarrollado en el proyecto europeo de investigación PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, en portugués), el cual se ha desarrollado de forma cooperativa por la Universidad de Sevilla (España) y la Universidad del Algarve...

A project named PERSISTAH is being developed to study the seismic vulnerability of primary schools in Huelva (Spain) and the Algarve (Portugal). This area has a moderate seismicity but this is affected by a nearby area where earthquakes of large magnitude (Mw≥6) and longreturn periods happen. The seismic vulnerability of URM (UnReinforced...

Spanish primary school buildings are likely to present a high seismic vulnerability. This is due to two main factors: (a) most of them were built prior to the enforcement of the Spanish seismic codes; (b) the elevated child-to-adult ratio compromises the effectivity of the evacuation plans. In this work, the schools of the Spanish province of...
