A novel holistic approach for the seismic-energy performance assessment of maso...
Furtado, A.; Rodrigues, H.; Rodrigues, M. F.; Arêde, A.; Varum, H.The masonry infill walls are often used in the envelopes of reinforced concrete buildings for different purposes, but a large part of them was built before the enforcement of modern seismic and/or energy codes. Due to that, the envelope of the reinforced concrete buildings is responsible for the energy consumption needed for indoor heating and cooling. At the same time, recent earthquakes proved that the infill...
Characterisation of Portuguese RC Precast Industrial Building Stock
Rodrigues, H.; Sousa, R.; Vitorino, H.; Batalha, N.; Varum, H.; Fernandes, P.The construction of a vulnerability model requires reliable information on the features of the buildings in the study. The purpose of this work is the characterisation of the precast industrial buildings in Portuguese industrial park, based on the survey of 73 design projects of existing buildings. The collected data are based on a previous study on the features that influence the seismic response of this type ...
Perspectives and approaches for the out-of-plane testing of Masonry Infill Walls
Furtado, A.; Arêde, A.; Melo, J.; Rodrigues, H.; Pinto, N.; Varum, H.It is widely accepted that further and more in-depth research is required on the out-of-plane seismic response of masonry infill walls to increase knowledge regarding this particular behaviour and to develop effective strengthening strategies for preventing their collapse. However, such experimental tests are difficult to perform and the scientific community recognizes the complexity inherent to the test appara...

Experimental study of the out-of-plane behaviour of masonry infill walls with a...
Furtado, A.; Arêde, A.; Varum, H.; Rodrigues, HugoRecent earthquakes demonstrated a significant contribution of the masonry infill walls in the structural response of the existent reinforced concrete buildings. When subjected to seismic actions, they tend to interact with the surrounding RC frames, which can result in different failure modes depending on the combination of the in-plane and the out-of-plane behaviour. From the surveys on damaged and collapsed R...
Seismic behavior of RC building structures designed according to current codes
Mosleh, A.; Rodrigues, Hugo; Varum, H.; Costa, A.; Arêde, A.Earthquakeswhich recently occurred in highly populated regions showthat existing buildings constructed without appropriate seismic resisting characteristics may constitute as an important source of risk and may cause economical loses and casualties. It is recognized the progress of the knowledge in earthquake engineering in the last decades. In this paper, two 6 irregular storey buildings were studied consistin...
Systematisation of seismic retrofitting in vernacular architecture
Lima, A.; Correia, M. R.; Gomes, F.; Carlos, G. D.; Viana, D; Lourenço, Paulo B.; Varum, H.This paper aims to identify and to systematize the data obtained during the working process of the research project 'SEISMIC-V –Vernacular Seismic Culture in Portugal' in terms of seismic- retrofitting elements earthquake -resistant reinforcement implemented in vernacular buildings. The data will be distinguished based on the structural seismic strengthening and according to the following criteria: strengthenin...
Common damages and recommendations for the seismic retrofitting of vernacular d...
Correia, M. R.; Varum, H.; Lourenço, Paulo B.This closure chapter acknowledges the most common retrofitting elements and measures identified in vernacular architecture. It enhances common systematic structural damage and failure mechanisms during earthquakes, relating them with probable causes, and establishing general recommend ations to consider in preventive and reactive actions. Also, recommendations for the design and detailing of new construction in...
Systematisation of seismic mitigation planning at urban scale
Viana, D. L.; Lima, A.; Carlos, G. D.; Gomes, F.; Correia, M. R.; Lourenço, Paulo B.; Varum, H.This chapter explores the relation between the seismic mitigation planning that was developed to contribute to minimise effects at urban scale, which arise within the seismic impact. In this sense, it deepens the notion that interdependence, solidarity and cohesion of the different morphological constituents promote a better prepared built fabric, when facing catastrophic phenomena of seismic origin. Preventive...
Assessment of the efficiency of prefabricated hybrid composite plates (HCPs) fo...
Esmaeeli, Esmaeel; Barros, Joaquim A. O.; Sena-Cruz, José; Varum, H.; Melo, J.The effectiveness of prefabricated hybrid composite plates (HCPs) as a seismic retrofitting solution for damaged interior RC beam-column joints is experimentally studied. HCP is composed of a thin plate made of strain hardening cementitious composite (SHCC) reinforced with CFRP sheets/laminates. Two full-scale severely damaged interior beam-column joints are retrofitted using two different configurations of HCP...
