Abstract(s)
Reinforced-concrete (RC) dual wall–frame structures comprise an important proportion of the building stock in some
European cities. However, many were constructed without seismic provisions and it is therefore important to assess
their ability to withstand seismic events and to define strategies to reduce their potential vulnerability. This work
focuses on the numerical simulation of the seismic behaviour of RC walls making use of fibre-based non-linear beam
elements. Even though it is common to assume perfect bond between reinforcing bars and concrete, the relative
bond–slip deformations between the two materials can contribute up to 40% of the total lateral deformation of
columns when ribbed rebars are used and up to 90% in the case of smooth rebars. The aim of this paper is to
provide a contribution towards understanding the importance of these effects in old RC walls and to provide
indications regarding the use of a simplified bond–slip model.
