Seismic Behavior of Lisbon Mixed Masonry-RC Buildings With Historical Value: A Contribution for the Practical Assessment

Abstract: The fact that linear analysis is still the most used procedure in the design engineering offices, studies which addresses issues associated to the estimation of the structural behavior factor values are relevant. In this study, the behavior factor of a particular type of mixed masonry-reinforced concrete buildings in Lisbon is estimated. The typology chosen in this study represents 30% of building stock in Lisbon; these buildings were built between 1930 and 1960 and thus were designed without considering the s… Show more

“…The tools for seismic assessment depend on whether a building's seismic behaviour is governed by either out-of-plane local mechanisms or overall shear behaviour of masonry walls [11][12][13]. The 20th century URM buildings are planned to have this latter behaviour, but it has only been in recent times that specific studies considered their actual seismic damage [14,15] or addressed the seismic assessment of the oldest examples (pre-1960) [16,17]. Their masonry structure ranges from random rubble to clay bricks and blocks, although a proper definition of mechanical properties is still missing, since (a) they do not respond to the typical conditions of 'old' masonry, described, e.g., in [18], as cement mortar being used instead of lime, and (b) load-bearing units come from a non-standard local production, and non-load-bearing material is often used as a structural material [19,20].…”
