Experimental campaign of horizontal cladding wall panels connection in industri...
Ostetto, Liana; Fonseca, Jorge; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoThe connections of cladding wall panels to precast reinforced concrete (PRC) buildings were identified as the source of several non-structural damages reported after recent earthquakes in Europe, highlighting their critical importance. The inadequate performance of these connections often leads to the collapse of cladding panels, resulting in significant economic losses and societal impacts. To better understan...
Influence of horizontal cladding wall panels in industrial precast RC buildings...
Ostetto, Liana; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoRecent earthquakes have highlighted the primary vulnerabilities of buildings constructed with precast reinforced concrete elements, particularly issues related to the connections of cladding panels, which have often led to the collapse of these components. In current design practices for precast reinforced concrete industrial buildings, the contribution of cladding panels is typically neglected, as they are ass...
Assessment of post-earthquake fire capacity of RC frames without seismic design
Vitorino, Hugo; Vila Real, Paulo; Sousa, Romain; Couto, Carlos; Rodrigues, HugoTo study the importance of post-earthquake fire events, 500 reinforced concrete (RC) frames were designed without seismic considerations. These consist in three-bays frames with a variation in the number of floors from two to six (100 frames each). Numerical analyses were performed in SAFIR to investigate the influence of different types of damage, damage location, fire location and fire curves on the post-eart...
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...
Influence and effectiveness of horizontal diaphragms and cladding wall panels o...
Ostetto, Liana; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoThe seismic behaviour of precast reinforced concrete industrial structures has been extensively investigated in recent decades, especially after the damage caused by recent earthquakes. The interaction of the roof’s horizontal diaphragm with the structural and non-structural elements can influence the seismic behaviour of these buildings. Thus, the present study aims to investigate this interaction, through non...
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...
Assessment of the Seismic Behavior of a Precast Reinforced Concrete Industrial ...
Ostetto, Liana; Sousa, Romain; Rodrigues, Hugo; A. L. Fernandes, PauloThe latest earthquakes in Europe exposed some critical problems in the connections of cladding panels in industrial precast reinforced concrete (PRC) structures. These connections did not perform as desired, causing the panels to fall, leading to significant nonstructural damage that resulted in the loss of human life and significant socio-economic impacts due to the interruption of business. Furthermore, in ad...
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...
