The analysis of buildings constructed in the last 20 years, designed following modern
standards, may lead to worrying conclusions. Images of out-of-plane expulsions and in-plane
failures of infill walls in recent seismic activities around the world reminded engineers of the
consequences of bad practice, wrong solutions or inadequate design.
With the above in mind, a research program is being conducted as a partnership between
University of Minho and the National Laboratory for Civil Engineering (LNEC), which
includes a shaking table experimental program of framed concrete buildings with masonry
infill walls, reinforced and unreinforced.
Herein the shaking table program and the tested solutions are detailed, along with the
discussion of the results, focusing on the local behaviour of the infills and the global
behaviour of the concrete structure
