“…In the late '90s, some experimental tests on different weak clay masonry infills in reinforced concrete frames have been executed in an extensive experimental research performed by Calvi and Bolognini [1]. Full-scale, single-storey, single-bay frame specimens were designed according to modern seismic code provisions and subjected to in-plane and out-ofplane tests.…”

“…(1) In 2006 several tests on AAC masonry infills have been conducted by Penna and Calvi [3], using the same RC frames of the research by Calvi and Bolognini [1]. Different AAC infills were tested: unreinforced, reinforced with a RC mid-height beam, reinforced with steel bars in the bed joints and with and without opening.…”

“…Penna and Calvi [3] have additionally carried out experiments of mechanical characterization on AAC units, hardened mortar and masonry wallets; some of them, in particular the vertical and the horizontal compression tests and diagonal compression tests (Figure 7a) on the masonry specimens, have been used in the present work to calibrate the numerical model. In 2006 several tests on AAC masonry infills have been conducted by Penna and Calvi [3], using the same RC frames of the research by Calvi and Bolognini [1].

“…The limitation of the infill damage induced by earthquake is of major interest for the prevention of extensive economic losses and possible threats to human lives. During the last decades several researches have been accomplished worldwide, and many different aspects have been investigated through experimental [9,10,11,12,13,14] and/or numerical [15,16,17,18,19] studies.…”

IntroductionAutoclaved Aerated Concrete (AAC) is a lightweight and energy‐efficient material which makes it one of the most convenient materials to be used in infill walls. Accordingly, AAC walls are becoming more and more favored infill systems in earthquake‐prone regions. Although the infills are not considered primary components in seismic design, they are highly susceptible to be damaged under seismic actions in in‐plane (IP) and out‐of‐plane (OOP) directions.ObjectivePast post‐earthquake site surveys indicated that the failure of infill walls may result in severe casualties, injuries, and economic losses. In addition, damage to infills may hinder the functionality of critical buildings, which are expected to be in service after earthquakes. The application of horizontal bed‐joint reinforcement between infill courses is one of the promising solutions to increase the seismic resilience of infill walls.MethodologyThis paper presents the experimental performance investigation of AAC infill walls with flat‐truss bed‐joint reinforcement being subjected to lateral loading in IP and OOP directions. The specimens represent relatively thin infills with a thickness of 150 mm, which are generally used in indoor environments. To consider the seismic actions in the IP direction, two full‐scale infill wall specimens (one unreinforced reference and one with flat‐truss reinforcement) built in reinforced concrete frames were first tested under reversed cyclic IP displacement reversals and then tested under the cyclic OOP displacements.ConclusionsThe results revealed that the use of flat‐truss reinforcement enhanced the OOP strength, ultimate displacement, and energy dissipation capacity of infill walls that have been subjected to cyclic IP displacements previously.
