Abstract

The continuum damage model proposed by Gambarotta and Lagomarsino (1997a, 1997b) focuses on modeling in-plane bed joint shearing in masonry walls. It is based on an analytical homogenization of bed joints and brick layers and distinguishes damage in mortar joints and brick units. The current paper addresses implementation and application aspects of this model. First the implementation of the model has been validated in a single integration point both in tension and compression. Local Newton-Raphson iterations have been avoided. A comparison between experimental and nonlinear finite element results are provided for masonry walls tested by Anthoine et al. (1995). Finally, the model is also applied in combination with shell elements to simulate out-of-plane behaviour. The two storey masonry building tested by Magenes et al. (1995) has been analysed. The response has been compared with previous numerical results using the sequentially linear analysis approach (DeJong et al., 2009).
