A document management system for the conservation of cultural heritage buildings
Lourenço, Paulo B.; Peña, Fernando; Amado, MiguelA document management system (DcMS) for the efficient organization and visualization of the data related to conservation projects in cultural heritage buildings applied to a case study is presented. The objective of the system is to allow for the interchange of information between different specialists, to prevent the loss of data through time and to promote technical awareness of general public. For this purpo...
Desempenho sísmico de um minarete de alvenaria
Mendes, N.; Lourenço, Paulo B.; Ramos, Luís F.; Peña, FernandoEsta comunicação apresenta a avaliação do desempenho sísmico do Qutb Minar, minarete em Nova Deli, Índia. A modelação numérica foi realizada com recurso a três modelos diferentes, calibrados através de ensaios de identificação dinâmica. A combinação de resultados dos modelos permitiu compreender melhor o comportamento do minarete e validar os modelos mais simples. No estudo do desempenho sísmico da estrutura fo...
Numerical models for the seismic assessment of an old masonry tower
Peña, Fernando; Lourenço, Paulo B.; Mendes, N.; Oliveira, Daniel V.The present paper describes the seismic assessment of the Qutb Minar in Delhi, India. Three models with different levels of complexity and simplifications were developed. The use of these models allows to overcome the complexity on the study of the seismic behavior of ancient masonry structures; by combining the results of the different models it is possible to obtain a better and more comprehensive interpretat...
Virtual reconstruction of Medieval monastery using CAD model
Amado, Miguel; Lourenço, Paulo B.; Peña, FernandoA 3D Computer-Aided Design (CAD) virtual reconstruction of the medieval monastery of Santa Maria de Salzedas (Portugal) is presented. This monastery is the second largest Cistercian monastery of Portugal. However, the majority of the monastery disappeared after the extinction of the religious orders in the Age of Enlightenment without letting any vestige, and with almost no existing documentation. In order to a...
Monastery of Salzedas (Portugal) : intervention in the cloister and informatio...
Lourenço, Paulo B.; Ramos, Luís F.; Vasconcelos, Graça; Peña, FernandoAnyone involved in the conservation of cultural heritage buildings is aware of the enormous amount of information generated by the different specialists, which is generally not handled adequately by owners and/or authorities involved in the process. The consequence is that valuable information is lost in a complex process of reaching a decision that involves many different experts and information tends to get f...
Experimental dynamic behavior of free standing multi-block structures under sei...
Peña, Fernando; Lourenço, Paulo B.; Costa, Alfredo CamposThis paper describes the dynamical behavior of free standing block structures under seismic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four single blocks of different geometry and associations of two and three blocks. The blocks, which are large stones of high strength blue granite, were subjected to free vibration, and harmonic and random motions o...

Seismic analysis of masonry monuments by an integrated approach that combines t...
Peña, Fernando; Casolo, Siro; Lourenço, Paulo B.The paper presents a strategy for the non-linear dynamical analysis of ancient masonry structures through two case studies ("Maniace Castle" in Syracuse, Italy and the Qutb Minar in Delhi, India).
Simulación numérica de estructuras formadas con grandes bloques de piedra
Peña, Fernando; Lourenço, Paulo B.; Lemos, José V.Este artículo presenta el modelado numérico de estructuras formadas con bloques de piedra. Este tipo de estructuras se deben representar como formadas por bloques rígidos, en vez de considerarlas como estructuras continuas. El Método de los Elementos Discretos (MED) es una herramienta efectiva en el modelado numérico de bloques rígidos. Aquí se propone una nueva metodología para encontrar los parámetros requeri...
On the dynamics of rocking motion of single rigid–block structures
Peña, Fernando; Prieto, Francisco; Lourenço, Paulo B.; Costa, Alfredo Campos; Lemos, José V.This paper describes the behavior of single rigid-block structures under dynamic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four blue granite stones with different geometrical characteristics under free vibration, and harmonic and random motions of the base. In total, 275 tests on a shaking table were carried out in order to address the issues of re...
