ABSTRACT
This paper reports an experimental study aiming at the analysis of the behaviour under horizontal actions of reinforced concrete frames infilled with different brick masonry walls. conducted at the Centre for Studies and Equipments in Earthquake Engineering (C3ES) of the National Laboratory for Civil Engineering of Portugal (LNEC).
Nine models, in a scale 2:3, were tested, named: two bare frames, four fully infilled frames and three infilled frames with a window opening. Two different horizontal histories of displacements under identical velocities were imposed at the level of the beam centreline: cyclic (six models) and monotonic (three models). Constant vertical forces were applied at the top of the columns in order to reproduce the effect of the upper floors of a building. The characteristics of the models, the test set-up and instrumentation and. the testing procedure are reported. Some results of this experimental study are also presented and analysed.
