Seismic damage and fragility of RC buildings. [PDF]
, 2023 Seismic actions cannot be predicted in time, location or intensity. Serious earthquake actions can cause the occurrence of different levels of damage of the elements and the structure as a whole, which can even lead to their collapse. The methods for evaluation of seismic performance of structures are discussed in this paper and the focus of the paper ...

Low cycle fatigue tests of reinforced concrete columns and joints built with ribbed reinforcement and plain stirrups [PDF]
, 2012 The majority of existing reinforced concrete (RC) buildings were built prior to the introduction of seismic codes. As observed in various recent earthquakes, due to their lack of structural capacity and ductility such structures are very vulnerable and
