Influence of retrofitting in the seismic behaviour of precast reinforced concre...
Ostetto, Liana; Batalha, Nádia; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoPrevious destructive earthquakes caused large economic losses as well as human losses. Seismic risk studies are of paramount importance to predict the impact of future earthquakes and support seismic risk mitigation policies. The present study presents a seismic risk assessment based on the cost and direct loss assessment of precast industrial buildings with different retrofitting levels in terms of horizontal ...
Retrofitting solution for beam-to-column connections of precast reinforced conc...
Rodrigues, Hugo; Batalha, Nádia; Furtado, André; Arêde, António; Sousa, Romain; Varum, HumbertoPrecast reinforced concrete building structures are widely used in the Portuguese industrial stock and throughout Europe. Beam-to-column connections are a key component in this type of structure. However, they are also the source of significant damage, as reported in recent earthquakes. Different configurations are common, such as using a dowel, neoprene or just assuming a concrete-to-concrete interface. Both a...
Seismic assessment of existing precast RC industrial buildings in Portugal
Batalha, Nádia; Rodrigues, Hugo; Sousa, Romain; Varum, HumbertoPrecast reinforced concrete (PRC) buildings are common on European industrial parks. In past earthquakes, namely in Italy and Turkey, this typology of buildings showed a poor performance, namely at structural level. One of the major concerns at structural level regards the connection between the beams and columns. Two types of beam-to-column connections are more common in this type of buildings: the pure fricti...
Cyclic behaviour of precast beam‐to‐column connections with low seismic detailing
Batalha, Nádia; Rodrigues, Hugo; Arêde, António; Furtado, André; Sousa, Romain; Varum, HumbertoBeam-to-column connections are a crucial element in industrial precast reinforced concrete (PRC) buildings. They are also the source of several damages reported after recent earthquakes. This typology of buildings is very common both in the Portuguese industrial park and throughout Europe. In order to have a better knowledge of the connection behaviour an extensive experimental work was done and it is here pres...
Influence of Beam-to-Column Connections in the Seismic Performance of Precast C...
Rodrigues, Rodrigo; Vitorino, Hugo; Batalha, Nádia; Sousa, Romain; Fernandes, Paulo; Varum, HumbertoPast earthquakes have brought attention to the poor performance of precast reinforced concrete structures, especially relating to beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is important. In the present work numerical analyses developed allowed the study of the effect that different story heights and connection prop...

Assessment of seismic behavior of an RC precast building
Vitorino, Hugo; Batalha, Nádia; Sousa, Romain; Fernandes, Paulo; Varum, Humberto; Rodrigues, HugoPast earthquakes brought attention to the poor performance of precast reinforced concrete structures. One of the problems observed in those structures is related to the beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is an important aspect that should be studied. The numerical analyses developed allowed the study of the...
