Advantages of structural inspection and diagnosis for traditional buildings’ re...

This work demonstrated, through Life Cycle Assessment (LCA), the environmental advantages brought by the application of the Structural Inspection and Diagnosis (SID) methodology to the structural refurbishment of 7 traditional buildings located in the city of Porto (Portugal), when compared to the common total demolition and reconstruction approach. The early diagnosis of the conservation state of the existing ...

Methods and challenges on the out-of-plane assessment of existing masonry build...

Methods and approaches for blind test predictions of out-of-plane behavior of m...

Earthquakes cause severe damage to masonry structures due to inertial forces acting in the normal direction to the plane of the walls. The out-of-plane behavior of masonry walls is complex and depends on several parameters, such as material and geometric properties of walls, connections between structural elements, the characteristics of the input motions, among others. Different analytical methods and advanced...

In situ Out-of-Plane Cyclic Testing of Original and Strengthened Traditional St...

This article presents a field experimental campaign carried out on an existing one-story stone masonry building, aiming at characterizing the out-of-plane behavior of its walls. A bidirectional test set-up based on a self-equilibrated airbag system was developed and used on three similarmasonry walls under distinct conditions: original, retrofitted, and strengthened. The results obtained and the main advantages...

Methods and Challenges on the Out-Of-Plane Assessment of Existing Masonry Build...

Historic masonry buildings were built for many centuries taking into account mostly vertical static loads according to the experience of the builder, usually, without much seismic concern. The seismic behavior of ancient masonry buildings is particularly difficult to characterize and depends on several factors, namely the materials properties, geometry of the structure, connections between structural and non-st...

URBSIS: avaliação da vulnerabilidade e gestão do risco sísmico à escala urbana

A qualidade de vida nos núcleos urbanos constitui uma meta dinâmica, fortemente influenciada pelos processos sociais e económicos, pela evolução das suas exigências e expectativas e pela evolução do próprio tecido urbano, do parque edificado e das infraestruturas. Nos núcleos urbanos antigos, são peças fundamentais deste desafio a garantia do conforto e de salubridade, num equilíbrio que se quer, sustentado e s...

Avaliação da vulnerabilidade sísmica de núcleos urbanos antigos

Este artigo reúne alguns dos mais importantes outputs resultantes do projeto URBSIS, financiado pela Fundação para a Ciência e Tecnologia, nomeadamente aqueles relacionados com a avaliação da vulnerabilidade sísmica de núcleos urbanos antigos através da aplicação de uma metodologia simplificada baseada no cálculo de um índice de vulnerabilidade que, consequentemente, possibilita a avaliação de danos e a criação...

A simplified four-branch model for the analytical study of the out-of-plane per...

During the last years, several studies have been made aiming to assess the out-of-plane seismic response of unreinforced stone masonry structures. This fact led to the development of a wide variety of models and approaches, ranging from simple kinematic based analytical models up to complex numerical simulations. Nevertheless, for the sake of simplicity, the out-of-plane seismic response of a masonry wall pier ...

Experimental characterization of the out-of-plane performance of regular stone ...

Stone masonry is one of the oldest and most worldwide used building techniques. Nevertheless, the structural response of masonry structures is complex and the effective knowledge about their mechanical behaviour is still limited. This fact is particularly notorious when dealing with the description of their out-of-plane behaviour under horizontal loadings, as is the case of the earthquake action. In this contex...

Efficiency of strengthening techniques assessed for existing masonry buildings

The Azores archipelago is a zone with a vast cultural heritage, presenting a building stock mainly constructed in traditional stone masonry. It is known that this type of construction exhibits poor behaviour under seismic excitations; however it is extensively used in seismic prone areas, such as this case. The 9th of July of 1998 earthquake was the last seismic event in the islands, leaving many traditional st...
