Title: Structural assessment of a stone masonry wall using a continuum damage model and experimental validation
Issue Date: 2007
Abstract: Understanding how stone masonry structures behave under dynamic horizontalloads yields important information on possible collapse mechanisms and damage progressionalong the structure. With this in mind a numerical and experimental study was performedconcerning the structural behaviour of a stone masonry wall built in situ at the Laboratory ofSeismic and Structural Engineering (LESE). The wall was tested under cyclic horizontal loadto simulate the effects of a horizontal seismic action. The experimental response allowed assessingthe cyclic behaviour and estimating the energy dissipation and ductility capacity ofthe structure, as well as its strength and stiffness. Afterwards, the wall was simulated numericallyin Cast3M [1] using a finite element modelling strategy. The stones, the infill and thejoints were simulated considering them as part of a unique homogeneous material and usinga non-linear continuum damage model [2] to reproduce the walls global behaviour.The final objective of this work is to study the applicability of such continuum numericalmodels to simulate stone masonry structures, using experimental results as reference values.
