Earthquake magnitude prediction based on arti cial neural networks: a survey
(Croatian Operational Research Society, 2016)
The occurrence of earthquakes has been studied from many aspects. Apparently, earthquakes occur without warning and can devastate entire cities in just a few seconds, causing numerous casualties and huge economic loss. ...

K-means cluster for seismicity partitioning and geological structure interpretation, with application to the Yongshaba Mine (China)
(Hindawi, 2017-07-30)
Seismicity partitioning is an important step in geological structure interpretation and seismic hazard assessment. In this paper, seismic event location (X,Y,Z) and Euclidean distance were selected as the K -Means cluster, ...

Assessment of integrated solutions for the combined energy efficiency improvement and seismic strengthening of existing URM buildings
(MDPI, 2022-08-20)
The European building stock is an aging infrastructure, mainly built prior to building codes. Furthermore, 65% of these buildings are located in seismic regions, which need to be both energetic and seismically retrofitted ...

Optimal ductility enhancement of RC framed buildings considering different non-invasive retrofitting techniques
(Elsevier, 2021-09-01)
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 ...

Numerical modelling for the seismic assessment of complex masonry heritage buildings: the case study of the Giralda tower
(Springer, 2023-06-02)
Existing heritage buildings can be especially vulnerable to earthquakes. They were designed only considering gravity loads and some of them are located in earthquake prone areas, such as the southwestern Iberian Peninsula. ...

Fast seismic assessment of built urban areas with the accuracy of mechanical methods using a feedforward neural network
(MDPI, 2022)
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 ...

A comparative analysis between the Spanish and Portuguese seismic codes: application to a border RC Primary School
(David Publishing, 2020)
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 ...

A deterministic seismic risk macrozonation of Seville
(Springer, 2021-11-10)
The seismicity of the southwestern Iberian Peninsula is moderate but large events with long return periods occur (≈ 200 years). This exceeds the life of various generations, making the population unacquainted with the ...

Comparative study of alternative equivalent frame approaches for the seismic assessment of masonry buildings in OpenSees
(Elsevier, 2023-05-01)
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 ...
