Seismic Performance of Autoclaved Aerated Concrete (AAC) Masonry: From Experimental Testing of the In-Plane Capacity of Walls to Building Response Simulation

Fem Simulation of the Experimental Response of Aac Masonry Infills in Rc Frames

“…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. A type of AAC masonry similar to the one tested as infill has also been investigated by Costa et al [2], where in-plane cyclic tests, with cantilever boundary conditions, on load bearing masonry piers were performed at the University of Pavia on 4 panels with different dimensions and diverse applied vertical loads (Figure 7b). All the specimens were 2.75 m height and 0.30 m thick, however, the first 2 specimens had the same length (1.5 m) but they differed for the vertical load applied which was 200 kN and 300 kN, respectively.…”

“…In addition, in order to investigate the seismic response of load-bearing masonry piers, different in-plane cyclic tests have been executed in the framework of the research conducted by Costa et al [2].…”

“…Two of the cyclic tests conducted in the study performed by Costa [2] have been here considered. The analysis conducted on pier 1, the one with a vertical load of 200 kN, presented a rocking failure with a horizontal crack at the bottom part of the masonry wall; such a failure is very similar to the one observed during the tests.…”

Issues on the Use of Time-History Analysis for the Design and Assessment of Masonry Structures

“…Along the same ways, several examples of experimental studies can be found in the literature, where cyclic in-plane tests were performed on masonry piers aiming to describe the different deformation limits at the structural element level for the two damage modes (flexural/rocking and shear failure mode) of the in-plane response of masonry structures (e.g. [25], [26], [27], [16]). …”
