Refined Rigid Block Model for In-Plane Loaded Masonry by Daniele Baraldi, Claudia Brito De Carvalho Bello, Antonella Cecchi

“…The rigid block model is based on an existing discrete/rigid model with rigid blocks and elastoplastic interfaces that already proven its effectiveness in representing masonry behavior in linear and nonlinear fields. In this case, the proposed model is improved by assuming rigid quadrilateral elements connected by one-dimensional nonlinear interfaces, which are adopted both to represent mortar (or dry) joints between the blocks and also to represent inner potential cracks into the blocks. …”
